BAW56

BAW56 Description

The BAW56 from Taiwan Semiconductor Corporation is a high-performance general-purpose diode array designed for small-signal applications with a maximum DC reverse voltage (Vr) of 70V and an average rectified current (Io) of 200mA per diode. Packaged in a compact SOT-23 surface-mount form factor, it is ideal for space-constrained PCB designs. The device features a 1 Pair Common Anode configuration, making it versatile for various circuit topologies. With a low forward voltage drop (1.25V @ 150mA) and minimal reverse leakage current (2.5µA @ 70V), the BAW56 ensures efficient power handling and reduced energy losses. Its 6ns reverse recovery time (trr) enables fast switching, suitable for high-frequency applications.
