The 5 ns reverse recovery time (trr) tells you this is a fast-switching part — it recovers in the time it takes a typical 74HC gate to toggle once. A 5 ns trr means the diode sweeps out stored charge fast enough that you won't see a reverse-recovery spike in a 500 kHz switching regulator. Compare that to a standard recovery rectifier in the same package — that part would still be conducting 100 ns later, dumping shoot-through current into the FET. The BAT54JFILM is the part you reach for when the board has a switching node that needs a clean catch diode and the layout is tight. ## Active production, no end-of-life watch needed ROHS3 compliance is confirmed, so it passes the environmental screening for EU and North American builds without an exemption review. No official second-source cross-reference is published, but the BAT54 family is widely second-sourced by multiple manufacturers in the same SOD-323 footprint; a direct pin-compatible swap from another brand is straightforward if dual-sourcing becomes a priority. For volume production or urgent BOM fills, submit an RFQ with your target quantity and date code preference.","metaTitle":"BAT54JFILM Schottky Diode, 40 V, 300 mA, SOD-323, 5 ns trr","metaDescription":"STMicroelectronics BAT54JFILM Schottky diode: 40 V reverse, 300 mA forward, 5 ns trr, SOD-323.

The BAT54S is a series-connected pair of Schottky diodes in SOT-23. They are not pin-compatible — the package and circuit topology differ. Choose the single if you need one clamping diode; choose the series pair if you need a dual common-cathode or common-anode configuration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BAT54JFILM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BAT54JFILM when reusing this data.
