TIP32C

TIP42C is STMicroelectronics’ 100 V PNP power transistor in TO-220 — 6 A continuous, 65 W with a heatsink — the exact PNP complement to the TIP41C, for push-pull audio output stages, H-bridge high sides, and PNP series regulators. The ‘C’ suffix is the 100 V grade (TIP42 40 V / A 60 V / B 80 V / C 100 V): same current and package across grades, so match the grade to your rail voltage. Selection advice: pair with TIP41C (same 100 V / 6 A / TO-220, in this catalog) for complementary designs — but keep both halves in the same manufacturer family, since hFE spreads (15–75) differ between vendors and unmatched pairs distort. The 65 W rating needs a real heatsink; a bare TO-220 in still air is good for roughly 2 W. VCE(sat) reaches 1.5 V at 6 A, so budget the conduction loss in efficiency-sensitive designs. Active, stocked in tube packing.

ST lists BD140 as ACTIVE (in volume production) — a PNP silicon power transistor, SOT-32 (TO-126) plastic package. The TO-126 package positions it between small-signal transistors and TO-220 power devices: medium power handling in a compact footprint for driver stages. Selection advice: the complementary NPN is the BD139 — for push-pull stages, pair them from the same manufacturer to keep characteristics matched. Verify collector dissipation against the package thermal limits with margin. Parameters verified against the ST official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

MJ2955 is an ST PNP power transistor in TO-3 (TO-204AA) metal-can — VCEO 60 V, continuous collector current 15 A, the PNP complement of the 2N3055. The complementary pair is the selection point: MJ2955 with 2N3055 forms the classic push-pull output stage for audio amplifiers and complementary linear regulators — one cannot be substituted by the other, they are a matched NPN/PNP pair. Selection advice: lifecycle warning — ST lists the MJ2955 as obsolete (out of production); for repairs and legacy builds we source remaining distributor stock, and for new designs use current-production complementary pairs. In push-pull stages replace both devices together to keep the pair matched. Evidence: ST data confirms PNP, TO-3, obsolete status, complementary to 2N3055. Match the full MJ2955 code on your BOM.

BCP53-16TX is a Nexperia 80V, 1A PNP medium-power transistor — for linear regulators, high-side switches and power management: SOT223 (SC-73) SMD package, 650mW total power dissipation, hFE 100 to 250 gain selection, 150C maximum junction temperature, AEC-Q101 qualified. The SOT223 package delivers 1A switching capability in a surface-mount footprint, so designs gain through-hole-class current handling without hand assembly; the -16 gain bin (100-250) suits driver stages where predictable gain matters more than maximum beta. Business impact: medium-power PNPs are the workhorse of discrete power design — linear regulator pass elements, relay drivers and load switches all standardize on this footprint, so multi-sourcing is straightforward and pricing stays competitive. Selection advice: the -16 suffix selects the 100-250 hFE bin — for wider tolerance use the base BCP53 (63-250); the TX code denotes the standard packing — for automotive PPAP flows specify the -Q variant. Ranked #5 on the hqbuy.com real-time hot list (2026-10-05). Parameters verified against Nexperia documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

STGP19NC60HD is a STMicroelectronics very fast IGBT in TO-220 — for hard-switching power stages: motor drives, UPS and induction heating. 600 V collector-emitter, 19 A continuous at 100°C (40 A at 25°C), very soft ultra-fast recovery antiparallel diode, PowerMESH technology for the switching/on-state trade-off. Heat evidence: IGBT sourcing is active as Nexperia supply disruption pushes buyers toward ST and Infineon alternatives — ST online store and DigiKey carry stock with 20-week factory lead times reported. Selection advice: the P suffix is TO-220 through-hole — the same die ships as STGB19NC60HDT4 (D²PAK) and STGW19NC60HD (TO-247); match the package to your heatsink layout, the three are not footprint-compatible. Parameters verified against STMicroelectronics datasheet DS4967. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

STP16NF06 is an ST N-channel power MOSFET — 60 V, 16 A, RDS(on) 0.08 Ω, TO-220, STripFET II technology. The 60 V / TO-220 combination is the selection point: a workhorse switch for 24–48 V motor drives, DC-DC and load switching — through-hole for easy heatsinking. Selection advice: ST lists the STP16NF06 as Active. At 16 A the 0.08 Ω on-resistance dissipates over 20 W — a heatsink is mandatory, and verify the thermal design against the RthJC. For lower loss in the same footprint consider a newer-generation 60 V MOSFET; for SMD assembly the STD16NF06 (DPAK) is the surface-mount sibling. Evidence: ST data confirms Active, 60 V, 16 A, 0.08 Ω, TO-220, STripFET II. Match the full STP16NF06 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

STP36NF06L is an STMicroelectronics 60 V N-channel STripFET II power MOSFET in TO-220 — for 12/24 V rails, motor control and power switching: 100% avalanche tested. 30 A continuous drain current, 32 mΩ typical Rds(on), -55°C to +175°C junction range, Ecopack2 RoHS compliant. Heat evidence: automotive MOSFETs are on allocation watch as vehicle makers dual-source away from disrupted suppliers — AEC-Q101 parts with stable supply are prioritized. Selection advice: the L suffix denotes logic-level-friendly gate threshold (2.5 V max) — vs the IRF540N it offers tighter Rds(on) for 12/24 V systems; confirm your gate drive can deliver the required current for fast switching. Parameters verified against STMicroelectronics documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TIP121 is an ST NPN power Darlington transistor in TO-220, tube — for driving motors, relays and solenoids directly from MCU outputs. The Darlington pair is the selection point: minimum DC current gain of 1000, so a few milliamps of base drive switches 5 A loads — no separate driver stage needed. Selection advice: ST lists the TIP121 as Active (in volume production). Its complement is the TIP126 (PNP) — for push-pull stages specify the pair together. Note the Darlington VCE(sat) of ~2 V at full load: at 5 A it dissipates ~10 W, so a heatsink is mandatory, and it is not a low-dropout switch — for efficient switching consider a MOSFET instead. Evidence: ST data confirms Active status, NPN Darlington, TO-220. Match the full TIP121 code — the TIP122 (100 V) and TIP120 (60 V) are different voltage grades. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TIP122 is an STMicroelectronics NPN silicon power Darlington transistor — 5 A collector current, 100 V collector-emitter voltage, minimum DC current gain of 1000, in TO-220, tube packing, junction temperature to 150 °C. The Darlington gain of 1000 is the selection point: a microcontroller pin can switch multi-ampere loads (DC motors, solenoids, relays, lamps) through a small base resistor, where a single BJT would need far more base drive. Selection advice: Darlington saturation voltage reaches up to 4 V at 5 A — budget that voltage drop and the resulting heat, and fit a heatsink for continuous high-current loads. The PNP complement is the TIP127 for push-pull or H-bridge designs; for lower saturation choose a MOSFET instead. ST lists TIP122 as Active. Evidence: ST TIP122 datasheet and distributor listings confirm 5 A, 100 V, hFE 1000, TO-220 and tube packing. Match the full TIP122 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TIP127 is an STMicroelectronics PNP silicon power Darlington transistor — 5 A collector current, 100 V collector-emitter voltage, minimum DC current gain of 1000 at 3 A, in TO-220, tube packing, junction temperature −65 to +150 °C. The Darlington gain of 1000 is the selection point: a microcontroller pin can switch multi-ampere PNP-side loads (high-side relays, lamps, DC motors, LED drivers) through a small base resistor, where a single PNP would need far more base drive. Selection advice: TIP127 is the PNP complement of the NPN TIP122 — use the pair for push-pull or H-bridge output stages. Watch the Darlington saturation voltage (up to 2 V at 3 A, 4 V at 5 A): budget that drop and fit a heatsink for continuous high-current loads, since the 65 W rating only holds at 25 °C case temperature with proper cooling. For lower saturation choose a P-channel MOSFET instead. ST lists TIP127 as Active. Evidence: ST TIP127 datasheet and official product page confirm 5 A, 100 V, hFE 1000, TO-220 and tube packing. Match the full TIP127 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
