SMAJ20CA Description

Short technical summary and product information.

The SMAJ20CA is a bidirectional Zener TVS diode from Littelfuse designed for general purpose transient voltage suppression. It features a reverse standoff voltage of 20 V and a maximum clamping voltage of 32.4 V at a peak pulse current of 12.3 A. The device delivers a minimum peak pulse power of 400 W for a 1 ms pulse.

 

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 -65°C to +150°C. The bidirectional configuration protects circuits from voltage transients in both directions.

 

Typical applications include general purpose circuit protection in computing, communication, and industrial equipment. The part is RoHS compliant and has an MSL rating of 1 (unlimited).
