BAT54S,215

BAT54 is a Schottky barrier diode in SOT-23 — 30 V continuous reverse voltage, 200 mA continuous forward current, 240 mV forward voltage at 0.1 mA, 5 ns reverse recovery, 600 mA surge, guard ring for transient and ESD protection, -65 to +150 °C. The Schottky construction is the selection point: ~240 mV forward drop instead of ~700 mV silicon drop for low-loss blocking and clamping, plus 5 ns recovery for high-speed switching. Selection advice: BAT54 is the single-diode SOT-23 version (pin 2 is no-connect) — BAT54A, BAT54C and BAT54S are dual-diode variants with different pinning, so match the full BAT54 code for diode configuration. Evidence: NXP/Diodes Incorporated BAT54 datasheets and distributor listings confirm Schottky, 30 V, 200 mA, 240 mV Vf and SOT-23. Match the full BAT54 code.

1N5817 is a JEDEC-registered Schottky rectifier diode — 20 V reverse voltage, 1 A average rectified current, forward drop maximum 0.45 V at 1 A, DO-41 axial package, −65 °C to +125 °C. The low forward drop is the selection point: roughly half the loss of a PN diode at 1 A — the default Schottky for reverse-polarity protection and low-voltage rectification. Selection advice: lifecycle note — onsemi lists its axial 1N5817 variants as Obsolete, but the 1N5817 is a multi-source JEDEC number; for ongoing production specify a current-production 1N5817 from an active manufacturer. Voltage-grade siblings 1N5818 (30 V) and 1N5819 (40 V) share the package — pick the grade that covers your rail with margin, since Schottky leakage rises with voltage and temperature. Evidence: onsemi/Vishay datasheets confirm 20 V, 1 A, 0.45 V VF, DO-41. Match the full order code on your BOM. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SB560 is an onsemi 5 A Schottky barrier rectifier — VRRM 60 V, forward drop maximum 0.67 V, DO-201AD axial package. The 5 A rating in an axial package is the selection point: through-hole high-current rectification and reverse-polarity protection where SMD is not an option. Selection advice: lifecycle note — onsemi lists the SB560 as Obsolete; for ongoing production specify a current-production SB560 from an active manufacturer or the SMD equivalent. At 5 A the 0.67 V drop dissipates over 3 W — provide adequate copper or heatsinking, and verify the DO-201AD footprint against the DO-41 (smaller) and DO-27 variants, which are not interchangeable. Evidence: distributor data confirms onsemi SB560 Obsolete, 5 A, 60 V, DO-201AD. Match the full SB560 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SS210 is a Taiwan Semiconductor planar Schottky rectifier — VRRM 100 V, 2 A average forward current, SMB (DO-214AA) surface-mount package, 150 °C max junction. The 100 V top grade in SMB is the selection point: the highest-voltage 2 A Schottky in the compact SMB footprint for 48 V telecom and industrial rails. Selection advice: Taiwan Semiconductor lists the SS210 as Active. The SS2x family shares the SMB footprint across voltage grades — SS24 (40 V) through SS210 (100 V): one layout serves the whole range, so pick the grade that covers your rail with margin. At 100 V Schottky reverse leakage is significant — verify the leakage current against your standby and thermal budget. Evidence: Taiwan Semiconductor data confirms Active, 2 A, 100 V, SMB, 150 °C junction. Match the full SS210 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SS26 is a Taiwan Semiconductor planar Schottky barrier diode — VRRM 60 V, 2 A average forward current, SMB (DO-214AA) surface-mount package, 150 °C max junction. The 2 A rating in SMB is the selection point: compact SMD rectification for 24–48 V rails where a 40 V diode leaves too little margin. Selection advice: Taiwan Semiconductor lists the SS26 as Active. The SS2x family shares the SMB footprint across voltage grades — SS24 (40 V), SS26 (60 V), SS28 (80 V), SS210 (100 V): one layout serves the whole range, so pick the grade that covers your rail with margin. At 2 A provide adequate copper under the SMB pads. Evidence: Taiwan Semiconductor data confirms Active, 2 A, 60 V, SMB, 150 °C junction. Match the full SS26 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SS28 is an onsemi Schottky rectifier — 80 V reverse voltage, 2 A average rectified current, forward drop 850 mV at 2 A, DO-214AA (SMB) surface-mount package, −65 °C to +125 °C junction. The 80 V grade in SMB is the selection point: the higher-voltage member of the 2 A SMB Schottky family for 48 V rails and industrial supplies. Selection advice: onsemi lists the SS28 as Active (DigiKey SS28TR-ND). The 2 A SMB family shares the footprint across voltage grades — SS24 (40 V), SS26 (60 V), SS28 (80 V), SS210 (100 V): pick the grade that covers your rail with margin, since one layout serves the whole range. Note the 400 µA reverse leakage at 80 V — verify it against your standby budget. Evidence: DigiKey confirms onsemi SS28 Active, 80 V, 2 A, 0.85 V VF, SMB. Match the full SS28 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SS34-E3/57T is a Vishay 40 V / 3 A Schottky barrier rectifier in SMC (DO-214AB), tape and reel — for low-voltage power conversion: DC-DC output rectification, freewheeling and reverse-polarity protection. 0.5 V forward voltage at 3 A is the selection point: Schottky drop cuts conduction loss roughly in half versus a standard PN rectifier at the same current. Selection advice: the E3/57T suffix denotes tape and reel packaging — quote the full suffix to get reel rather than bulk; the onsemi SS34 on this site is the same 40 V / 3 A SMC footprint from a second manufacturer, giving a cross-source option for supply resilience. 100 A surge capability, −55 °C to +125 °C. Vishay lists this part as Active through distribution. Parameters verified against Vishay documentation 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.

SS36 is an onsemi Schottky barrier rectifier — VRRM 60 V, 3 A average rectified current, forward drop maximum 0.75 V, SMC (DO-214AB) surface-mount package. The 3 A rating in SMC is the selection point: mid-current SMD rectification for power supplies and reverse-polarity protection without the bulk of an axial diode. Selection advice: onsemi lists the SS36 as Active. The SS3x family shares the SMC footprint across voltage grades — SS34 (40 V), SS36 (60 V), SS310 (100 V): pick the grade that covers your rail with margin, since one layout serves the whole range. At 3 A the forward loss exceeds 2 W — provide adequate copper pour under the SMC pads. Evidence: distributor data confirms onsemi SS36 Active, 3 A, 60 V, SMC. Match the full SS36 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SS54 is a Yangjie Schottky barrier diode — 40 V reverse voltage, 5 A average rectified current, forward drop maximum 0.6 V, SMC (DO-214AB) surface-mount package. The 5 A rating in SMC is the selection point: high-current SMD rectification for power supplies and reverse-polarity protection without through-hole bulk. Selection advice: Yangjie lists the SS54 as Active. The SS5x family shares the SMC footprint across voltage grades — SS54 (40 V), SS56 (60 V): pick the grade that covers your rail with margin. At 5 A the forward loss reaches 3 W — provide generous copper pour under the SMC pads, and note Schottky reverse leakage rises sharply with temperature, so verify the thermal design at your worst-case ambient. Evidence: Yangjie data confirms Active, 5 A, 40 V, 0.6 V VF, SMC. Match the full SS54 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

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.
