BAT54

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.

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.

MMBT2222A is an onsemi NPN small-signal switching transistor in SOT-23 — 40 V collector-emitter voltage, 600 mA continuous collector current, DC current gain of 100 minimum, 300 MHz transition frequency, 350 mW dissipation, -55 to +150 °C, tape-and-reel packing. The SOT-23 package is the selection point: the SMD version of the classic 2N2222A for reflow assembly, keeping the same 40 V/600 mA ratings in a fraction of the board area. Selection advice: the A suffix is the higher-voltage grade — the plain MMBT2222 is only 30 V, so match the full MMBT2222A code. The 350 mW dissipation is lower than the TO-92 version, so derate switching loads accordingly. Evidence: onsemi/Diodes MMBT2222A datasheets and distributor listings confirm NPN, 40 V, 600 mA, 300 MHz and SOT-23. Match the full MMBT2222A code — the A suffix matters for voltage rating.
