BCP53-16TX

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.

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.

ST lists TIP32C as ACTIVE (in volume production) — a silicon epitaxial-base PNP power transistor, TO-220 package, whose complementary NPN is the TIP31C. The C voltage grade is the selection point: the TIP32 family spans grades with different voltage ratings in the same TO-220 package, so match the full TIP32C code — a lower-grade sibling is visually identical. Selection advice: for push-pull output stages, pair with the TIP31C from the same manufacturer to keep the complementary pair matched. Verify collector voltage and current against the C-grade ratings with thermal margin, and plan heatsinking. 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.

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.

2N7002,235 is Nexperia’s SOT-23 (TO-236AB) version of the classic 2N7002 N-channel MOSFET — 60 V / 300 mA — for small-signal switching, level shifting and load switching on space-constrained boards. The ‘,235’ suffix is Nexperia’s tape-and-reel packing code (3,000 per reel), not a different electrical part: ordering 2N7002,215 gets cut tape of the same die. Selection advice: the 5 Ω RDS(on) is high by modern standards, so keep continuous current well under the 300 mA headline rating to avoid I²R heating; for lower drop in the same footprint consider 2N7002P (1.6 Ω) or BSS138. VGS(th) is 2.5 V maximum, which 3.3 V logic can drive — but only marginally across temperature — so use a 5 V gate rail or a true logic-level part when the MCU supply is 3.3 V and the temperature range is wide. Active status through distribution; match the reel quantity to your run size before quoting. Parameters trace to the manufacturer datasheet; state quantity, packing and date-code requirements in your RFQ — we reconfirm the offered lot before quotation and reply within 24 hours.

BAT54S,215 is a Nexperia dual series Schottky diode in SOT-23, tape and reel — for ultra-high-speed switching, clamping and reverse-polarity protection in tight layouts. Two 30 V / 200 mA Schottky diodes with 5 ns reverse recovery in one SOT-23 is the selection point: series connection suits bidirectional clamping and bridge legs without a second package. Selection advice: the S denotes series — the BAT54 family also ships as BAT54 (single), BAT54A (common anode) and BAT54C (common cathode); confirm the pinout letter against your schematic before substituting, they are not interchangeable. The ,215 suffix denotes tape and reel. AEC-Q101 qualified. −65 °C to +150 °C. Nexperia lists this part as Active through distribution. Parameters verified against the Nexperia datasheet and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

BC847B is a Nexperia NPN general-purpose transistor — 45 V, 100 mA, gain group B (hFE 200–450), SOT-23 (TO-236AB) package, 150 °C max junction. The gain group B is the selection point: the middle gain bin of the BC847 family (A: 110–220, B: 200–450, C: 420–800) — the default choice for small-signal switching and amplification where the gain bin matters for bias stability. Selection advice: Nexperia lists the BC847B as in production. Match the gain group on the BOM — substituting a BC847C changes the bias point of a designed stage. Its PNP complement is the BC857B for complementary stages. The BC847 is the 45 V member of the family — its siblings BC848 (30 V) and BC849 (30 V, low noise) are lower-voltage, not upgrades. Evidence: Nexperia data confirms in-production, 45 V, 100 mA, gain group B, SOT-23. Match the full BC847B code — the gain letter changes the part.

BC847C,215 is Nexperia’s highest-gain grade of the BC847 NPN general-purpose transistor — 45 V / 100 mA in SOT-23 — with DC current gain hFE 420–800 (minimum 420 at 2 mA, 5 V). The ‘C’ is the gain rank: A covers 110–220, B covers 200–450, and C covers 420–800; ‘,215’ denotes tape-and-reel packing of the same die. AEC-Q101 qualified, which makes the C grade a defensible pick for automotive-adjacent small-signal stages. Selection advice: BC847C is footprint- and pin-compatible with BC847A/B, but dropping a lower grade into a bias-sensitive amplifier stage shifts the operating point — re-check base bias when substituting grades. For pure switching the grade barely matters, and BC847B is usually cheaper and better stocked. Pair with the PNP complement BC857C for push-pull or complementary driver stages.

PESD3V3S1UB is a Nexperia unidirectional ESD protection diode in SOD-523 — for single-line ESD defense on 3.3 V rails: SIM cards, sensor lines and low-voltage logic. 30 kV ESD rating with 20 V maximum clamping in a 1.6 x 0.8 mm package is the selection point: protection that fits where SOD-323 will not. Selection advice: unidirectional suits lines with defined polarity — for bipolar or AC-coupled lines, the bidirectional PESD5V0S1BA on this site is the correct pick; note its 207 pF capacitance is higher than the 5V0S1BA 45 pF, so avoid it on high-speed differential pairs. The ,115 suffix denotes tape and reel. −65 °C to +150 °C. Nexperia lists this part as Active through distribution. Parameters verified against the Nexperia datasheet and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

PESD5V0S1BA is a Nexperia bidirectional ESD protection diode in SOD-323 — for single-line ESD defense on 5 V interfaces: USB, HDMI control lines and keypads. 30 kV ESD rating with 14 V clamping and 45 pF capacitance is the selection point: it survives direct ESD strikes while staying small enough for one signal line. Selection advice: this is the bidirectional, 5 V, low-capacitance member of the pair — against the PESD3V3S1UB on this site (unidirectional, 3.3 V, 207 pF in smaller SOD-523), choose the 5V0S1BA for 5 V rails and faster edges where capacitance matters, the 3V3S1UB where the rail is 3.3 V and the line has defined polarity. The ,115 suffix denotes tape and reel. 130 W peak pulse power, −65 °C to +150 °C. Nexperia lists this part as Active through distribution; the -QF suffix (not this part) is the AEC-Q101 variant. Parameters verified against the Nexperia datasheet and distributor listings.
