BAT54A

BAT54A Description

The BAT54A from Diotec Semiconductor is a Schottky diode array configured as 1 Pair Common Anode, designed for high-efficiency rectification in low-voltage, high-speed switching applications. With a maximum reverse voltage (Vr) of 30V and an average rectified current (Io) of 200mA per diode, it is optimized for small-signal and power management circuits. The device features a low forward voltage drop (1V @ 100mA) and ultra-fast reverse recovery time (5 ns), minimizing power losses and improving transient response. Packaged in a SOT-23 surface-mount form factor, it is ideal for space-constrained designs and automated assembly processes.

BAT54A Features
