Each diode handles 300 mA DC average rectified current with a 40 V reverse voltage ceiling, and the 5 ns reverse recovery time keeps switching losses low in high-frequency rectification or clamping circuits. Forward voltage peaks at 900 mV at 100 mA — that's the worst-case drop for thermal budgeting in a low-voltage rail. Reverse leakage is 1 µA at 30 V, which stays manageable up to the 150°C junction limit, though leakage climbs with temperature.","metaTitle":"STMicroelectronics BAT54CFILM Schottky Diode, 40V, 300mA","metaDescription":"STMicroelectronics BAT54CFILM Schottky diode array, 40V reverse voltage, 300mA average rectified current per diode, 5ns trr, SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","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":"Active","lifecycle_stage":"eol_hot","Base Product Number":"BAT54","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"SOT-23-3","Reverse Recovery Time (trr)":"5 ns","Current - Reverse Leakage @ Vr":"1 µA @ 30 V","Voltage - DC Reverse (Vr) (Max)":"40 V","Operating Temperature - Junction":"-40°C~150°C","Voltage - Forward (Vf) (Max) @ If":"900 mV @ 100 mA","Current - Average Rectified (Io) (per Diode)":"300mA (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3600","priceTiers":[{"qty":1,"price":"$0.36000","currency":"USD"},{"qty":10,"price":"$0.25500","currency":"USD"},{"qty":100,"price":"$0.12860","currency":"USD"},{"qty":500,"price":"$0.10488","currency":"USD"},{"qty":1000,"price":"$0.07782","currency":"USD"},{"qty":3000,"price":"$0.06547","currency":"USD"},{"qty":6000,"price":"$0.06260","currency":"USD"},{"qty":9000,"price":"$0.05414","currency":"USD"},{"qty":30000,"price":"$0.05312","currency":"USD"},{"qty":75000,"price":"$0.04399","currency":"USD"},{"qty":150000,"price":"$0.04331","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a45db93da6c352b18b3e390448765d10.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAT54CFILM/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time of BAT54CFILM?","answer":"The reverse recovery time is 5 ns, which qualifies it as a fast-recovery Schottky suitable for switching applications above 200 mA output current."},{"question":"Can BAT54CFILM replace BAT54C?","answer":"The BAT54CFILM is functionally identical to the base BAT54C — same common-cathode Schottky pair, same 40 V / 300 mA ratings, same SOT-23-3 footprint.
