Each diode is rated for a 30 V DC reverse voltage and can handle an average rectified current of 200 mA. The 5 ns reverse recovery time makes it suitable for high-speed switching applications like polarity protection, freewheeling, and clamping in low-power DC circuits. ## Lifecycle status — obsolete, sourced to order The BAT 54-05 B5003 is listed as obsolete by Infineon. The 30 V reverse voltage covers common 5 V, 12 V, and 24 V rails with margin — fine for low-voltage DC bus protection. The 200 mA per-diode average current handles small-signal loads like relay coils, logic-level switching, and signal clamping. Forward voltage drops 800 mV at 100 mA, which is typical for a Schottky at this current level and gives a lower forward loss than a standard silicon diode. Reverse leakage is 2 µA at 25 V, acceptable for most low-power circuits but worth noting if the diode sits across a high-impedance node in a battery-powered design. ## Package and footprint The SOT-23-3 package (also known as TO-236-3 or SC-59) is a standard three-lead surface-mount footprint. The supplier device package is PG-SOT23. This is a common, easily laid-out package for low-power discrete diodes.","metaTitle":"BAT 54-05 B5003 Schottky Diode, 30 V, 200 mA, Common Cathode","metaDescription":"Infineon BAT 54-05 B5003 Schottky diode, 30 V reverse voltage, 200 mA average rectified current, common cathode pair in SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Speed":"Small Signal =< 200mA (Io), Any Speed","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BAT 54","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"PG-SOT23","Reverse Recovery Time (trr)":"5 ns","Current - Reverse Leakage @ Vr":"2 µA @ 25 V","Voltage - DC Reverse (Vr) (Max)":"30 V","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"800 mV @ 100 mA","Current - Average Rectified (Io) (per Diode)":"200mA (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/944ade5fb10b87a57ec636101ba94c59.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BAT 54-05 B5003?","answer":"Infineon has not published an official successor for this order code.
