BAT54

BAT54 Description

The BAT54 is a Schottky barrier diode manufactured by SMC Diode Solutions, designed for high-efficiency rectification and switching applications. With a fast recovery time (≤500ns) and low forward voltage drop (1V @ 100mA), it minimizes power losses and enhances performance in high-speed circuits. The diode features a 30V reverse voltage (Vr) and 200mA average rectified current (Io), making it suitable for low-power, high-frequency applications. Its ultra-low reverse leakage current (2µA @ 25V) and low junction capacitance (10pF @ 1V, 1MHz) ensure minimal signal distortion, ideal for precision electronics. Packaged in a compact SOT523 surface-mount form factor, it is optimized for space-constrained designs.
