SM6T18CA Description

Short technical summary and product information.

The SM6T18CA is a bidirectional Zener TVS diode designed for general-purpose transient voltage suppression. It features a reverse standoff voltage of 15.3V and a maximum clamping voltage of 32.5V at a peak pulse current of 123A (8/20µs). With a peak pulse power rating of 600W, it provides robust protection against voltage transients.

 

This device is housed in a DO-214AA (SMB) surface-mount package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C. The SM6T18CA is RoHS3 compliant and has an MSL of 1 (unlimited).

 

Typical applications include general-purpose circuit protection in consumer, industrial, and communication equipment. The bidirectional configuration allows protection of both positive and negative voltage spikes.
