Its Schottky barrier construction delivers a fast 5 ns reverse recovery time and a low forward voltage drop of 800 mV at 100 mA, making it suited for high-speed switching applications such as polarity protection, freewheeling, and signal clamping in low-voltage circuits. The diode comes in a standard SOT-23-3 surface-mount package (PG-SOT23-3-11), compatible with common board-level footprints. The 30 V reverse voltage and 200 mA forward current define the operating envelope. This diode fits low-side rectification, flyback catch diodes in relay or solenoid drivers, and ESD clamping on signal lines up to 30 V. The 2 µA reverse leakage at 25 V is typical for a small-signal Schottky and acceptable for most battery-powered designs. The 10 pF junction capacitance at 1 V helps maintain signal integrity in fast digital or RF paths. ## Active lifecycle — no near-term EOL concern No last-time-buy or discontinuation notice is in effect. For dual-sourcing, the BAT54 series includes multiple pin-compatible variants (BAT54, BAT54A, BAT54C, BAT54S) that share the same SOT-23-3 footprint and can be cross-referenced for supply flexibility.","metaTitle":"Infineon BAT54B5000 Schottky Diode, 30 V, 200 mA, SOT-23-3","metaDescription":"Infineon BAT54B5000 Schottky diode, 30 V reverse voltage, 200 mA average rectified current, 5 ns trr, SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Speed":"Small Signal =< 200mA (Io), Any Speed","Series":"BAT54","Package":"Bulk","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"BAT54","Capacitance @ Vr, F":"10pF @ 1V, 1MHz","Supplier Device Package":"PG-SOT23-3-11","Reverse Recovery Time (trr)":"5 ns","Current - Reverse Leakage @ Vr":"2 µA @ 25 V","Voltage - DC Reverse (Vr) (Max)":"30 V","Current - Average Rectified (Io)":"200mA","Operating Temperature - Junction":"150°C","Voltage - Forward (Vf) (Max) @ If":"800 mV @ 100 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b7c802173d28f8dbcfa6f8f4cc35c30c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent or replacement for BAT54B5000?","answer":"The BAT54B5000 is part of the BAT54 series.
