SMBJ12 Description

Short technical summary and product information.

The SMBJ12 is a unidirectional Zener TVS diode designed to protect sensitive electronic equipment from voltage transients. It offers 600W peak pulse power capability (10/1000µs waveform) with a clamping voltage of 20.9V at 30.2A peak pulse current. The device features a fast response time of less than 1ps and provides ESD protection up to 30kV air and contact discharge per IEC 61000-4-2.

 

This TVS diode is housed in a DO-214AA (SMB) surface mount package, suitable for automated assembly. It operates over a wide temperature range of -65°C to 150°C. The part is RoHS compliant and halogen free, with matte tin lead-free plating.

 

Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The low incremental surge resistance and excellent clamping capability make it suitable for general purpose transient voltage suppression.
