BAT54

BAT54 Description

The BAT54 from Taiwan Semiconductor Corporation is a high-performance Schottky diode designed for small-signal applications with a maximum average rectified current (Io) of 200mA and a reverse voltage (Vr) of 30V. Packaged in a compact SOT-23 surface-mount form factor, it is optimized for high-speed switching with a low forward voltage drop (1V @ 100mA) and minimal reverse leakage current (2µA @ 25V). Its ultra-fast reverse recovery time (5ns) and low junction capacitance (10pF @ 1V, 1MHz) make it ideal for high-frequency circuits. Compliant with ROHS3 and REACH standards, it is widely used in consumer electronics, power management, and signal conditioning.
