BAT54C

BAT54C Description

The BAT54C from SMC Diode Solutions is a Schottky diode array configured as 1 Pair Common Cathode, designed for high-speed switching and low-power applications. Packaged in a compact SOT-23 surface-mount form factor, it offers 30V maximum reverse voltage (Vr) and 100mA average rectified current (Io) per diode. With a fast recovery time of ≤500ns and an ultra-low reverse recovery time (trr) of 5ns, it ensures efficient performance in high-frequency circuits. The device features a low forward voltage drop (1V @ 100mA), minimizing power losses, and exhibits low reverse leakage (2µA @ 25V), enhancing energy efficiency.
