SMAJ51CA Description

Short technical summary and product information.

The Bourns SMAJ51CA is a bidirectional Zener TVS diode designed for transient overvoltage protection in general purpose applications. It features a reverse standoff voltage of 51V and a maximum clamping voltage of 82.4V at a peak pulse current of 4.9A. The device is rated for a minimum peak pulse power of 400W (10/1000μs waveform).

 

This TVS diode is housed in a compact DO-214AC (SMA) surface mount package, suitable for automated assembly. It operates over a junction temperature range of -55°C to +150°C and offers steady state power dissipation of 1.0W at 75°C lead temperature. The device is RoHS compliant and provides ESD protection per IEC 61000-4-2 (Level 4), as well as EFT and surge protection per IEC 61000-4-4 and IEC 61000-4-5.

 

Typical applications include protection of sensitive electronics in computing, portable communications, and video equipment from voltage transients caused by lightning, inductive load switching, and electrostatic discharge.
