P4SMA51A Description

Short technical summary and product information.

The P4SMA51A is a 400W peak pulse power unidirectional Zener TVS diode from Taiwan Semiconductor. It provides a clamping voltage of 70.1V and a peak pulse current capability of 6A under a 10/1000µs waveform. The device is designed for surface mount assembly in a DO-214AC (SMA) package with J-bend terminals.

 

This TVS diode is suitable for general purpose transient voltage suppression in applications such as I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. It operates over a junction temperature range of -55°C to 150°C and has a fast response time of less than 1.0ps from 0V to breakdown voltage.
