SMBJ13CA 13V Bidirectional TVS Diode – SMB (DO-214AA)

Product Description:
The SMBJ13CA Bidirectional TVS Diode provides reliable surge and transient voltage protection for sensitive electronic circuits operating on a 13V supply line. Designed for fast response and high clamping efficiency, this diode safeguards ICs, MOSFETs, signal lines, and low-voltage electronics exposed to inductive switching, lightning surges, and ESD events.

With a reverse stand-off voltage of 13V, a breakdown voltage up to 15.9V, and a clamping voltage of 21.5V, it ensures robust suppression performance. Its 27.9A peak pulse current capability makes it suitable for demanding industrial, automotive, and communication systems. Packaged in a compact SMB (DO-214AA) footprint, it supports automated assembly and space-efficient PCB design.
