The P6SMB400CA is a bidirectional Transient Voltage Suppressor diode designed for surge and ESD protection in sensitive electronics. It features a breakdown voltage between 380V and 420V and a working peak reverse voltage of 342V. This device can dissipate a peak pulse power of 600W and provides a maximum clamping voltage of 548V at a peak pulse current of 1.1A. Housed in a surface-mount DO-214AA (SMB) package, it offers a fast response time suitable for protecting portable communications, computing, and video equipment against electrical overstress events.
