The P6SMB56A is a unidirectional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronics from voltage transients. It features a working peak reverse voltage of 47.8 V and a breakdown voltage range of 53.2 V to 58.8 V. The device has a peak pulse power rating of 600 W and provides a maximum clamping voltage of 77 V at a peak pulse current of 7.9 A, with a maximum reverse leakage of just 1 µA. Housed in a compact DO-214AA (SMB) package, it is ideal for surge and ESD protection in portable communications, computing, and video equipment.
