BAT54A

BAT54A Description

The BAT54A from Taiwan Semiconductor Corporation is a Schottky diode array configured as 1 Pair Common Anode, designed for high-efficiency, low-power applications. This surface-mount device is housed in a compact SOT-23 package and is optimized for small-signal switching with a maximum forward current of 200mA (DC) per diode and a reverse voltage rating of 30V. Its ultra-fast reverse recovery time (5 ns) and low forward voltage drop (1V @ 100mA) make it ideal for high-speed circuits where minimal power loss is critical. The diode is RoHS3 compliant, REACH unaffected, and supplied in Tape & Reel (TR) packaging for automated assembly.
