Dual Schottky in a SOT-23 — what this part is and where it fits
The Infineon BAT6405E6327HTSA1 is a dual Schottky diode array in a common-cathode configuration, housed in a PG-SOT23 surface-mount package. Each diode is rated for 40 V reverse voltage and 250 mA average rectified current, with a fast 5 ns reverse recovery time. The part is AEC-Q101 qualified and carries an Automotive grade, making it suitable for use in automotive electronics, industrial power supplies, and high-frequency switching circuits where Schottky's low forward voltage drop and fast switching are needed.
AEC-Q101 and Automotive grade — what the qualification means
AEC-Q101 qualification and the Automotive grade mean this part has passed the stress tests required for use in automotive electronic systems: extended temperature cycling, high-temperature reverse bias, and humidity testing. The junction temperature is rated to 150°C maximum, which covers under-hood and under-dash environments. For a BOM destined for a Tier-1 automotive supplier, having the AEC-Q101 mark on the diode saves a separate qualification step. The part is also ROHS3 compliant.
Sourcing and lifecycle
The BAT6405E6327HTSA1 is listed as Active in production. No last-time-buy or obsolescence notice is in effect. For a production BOM line, this part can be specified into new designs without near-term supply risk.
