The P6SMB250A is a unidirectional Transient Voltage Suppressor (TVS) diode from the P6SMB series, engineered to protect sensitive electronics from voltage transients. It features a breakdown voltage range from 237V to 263V and a working peak reverse voltage of 214V. This device provides robust protection with a maximum clamping voltage of 344V at a peak pulse current of 1.8A and exhibits a low reverse leakage current of just 1µA. Housed in a compact DO-214AA (SMB) package, it is ideal for applications in portable communications, computing, and video equipment requiring compliance with IEC standards for ESD, EFT, and surge protection.
