The 5 ns reverse recovery time makes it a fit for high-frequency switching, clamping, and protection circuits where the series pair provides a common-cathode-like topology in a single SOT-23-3 package. ## Forward drop and leakage — the BOM trade-offs Reverse leakage is specified at 500 nA at 30 V, a value that climbs with junction temperature — the 150°C maximum junction rating means the leakage current can dominate the thermal budget in a confined SOT-23-3 layout if the ambient is high.","metaTitle":"STMicroelectronics BAR43SFILM Schottky Diode Array","metaDescription":"ST BAR43SFILM Schottky diode array, 30V 100mA, 5ns trr, SOT-23-3.

The series topology in BAR43SFILM is useful for applications requiring higher reverse voltage blocking or specific clamping arrangements, whereas the BAT54 series offers different pinouts and lower forward voltage at similar current ratings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BAR43SFILM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BAR43SFILM when reusing this data.
