Product details

Automotive Schottky pair for 12 V / 24 V bus protection

The BAT54AWFILMY is a dual Schottky diode array in a common-anode configuration, rated for 40 V reverse voltage and 300 mA average rectified current per diode. The 5 ns reverse recovery time makes it suitable for high-frequency rectification and clamping in automotive ECUs, body controllers, and sensor interfaces.

AEC-Q101 grade and junction temperature range

This covers under-hood and cabin environments where thermal cycling and high ambient temperatures are routine.

SOT-323 footprint and tape-and-reel delivery

Supplied in SC-70 / SOT-323 surface-mount package.
