SMBJ18CA Description

Short technical summary and product information.

The SMBJ18CA is a 600W bidirectional transient voltage suppression (TVS) diode from Littelfuse Inc. Designed for general purpose surge protection, it provides a reverse standoff voltage of 18V and a maximum clamping voltage of 29.2V at a peak pulse current of 20.6A (10/1000µs waveform). The device features a Zener diode structure and is rated for a peak pulse power of 600W minimum.

 

This TVS diode is suitable for protecting sensitive electronics from voltage transients. It is packaged in a DO-214AA (SMB) surface mount package, making it compatible with standard pick-and-place assembly processes. The operating temperature range is -65°C to 150°C. The device is bidirectional, providing protection for both positive and negative transients.

 

Applications include general purpose circuit protection in consumer, industrial, and telecommunications equipment. The compact SMB package allows for space-efficient designs. The part is RoHS compliant and REACH unaffected (unverified).
