SMBJ51CA Description

Short technical summary and product information.

The SMBJ51CA is a bidirectional Zener-type transient voltage suppressor diode designed for general-purpose circuit protection. It features a reverse standoff voltage of 51 V and a maximum clamping voltage of 82.4 V at a peak pulse current of 7.3 A. The device can handle a minimum peak pulse power of 600 W under a 10/1000 μs waveform.

 

This TVS diode is suitable for protecting sensitive electronics from voltage transients induced by lightning, inductive load switching, and electrostatic discharge. It is not intended for power line protection. The device operates over a junction temperature range of -55°C to 150°C.

 

The SMBJ51CA is offered in a standard DO-214AA (SMB) surface-mount package, which is compatible with automated pick-and-place assembly processes. The package is RoHS3 compliant and has an MSL rating of 1 (unlimited).
