The P6SMB300A is a unidirectional Transient Voltage Suppressor (TVS) diode in a compact SMB package, engineered for overvoltage protection. It features a breakdown voltage between 285 V and 315 V and a working peak reverse voltage of 256 V. This device provides robust protection with a maximum clamping voltage of 414 V at a peak pulse current of 1.5 A and can handle a peak pulse power of 600 W. With its fast response time and surface-mount design, the P6SMB300A is well-suited for protecting sensitive electronics in applications like portable communications, computing, and video equipment from damage due to ESD, EFT, and surge events.
