SMBJ3V3CA TVS Diode – 3.3V Bidirectional Transient Suppressor (SMB Package)

Product Description:
The SMBJ3V3CA TVS Diode is a high-performance bidirectional transient voltage suppressor designed to protect 3.3V-powered sensitive electronics from voltage spikes generated by ESD, inductive load switching, and lightning-induced surges. With a reverse stand-off voltage of 4.1V, a breakdown voltage of 3.3V, and a clamping voltage of 7.3V, this TVS diode ensures reliable, fast, and robust overvoltage protection for low-voltage digital and analog circuits.

Encased in a compact SMB (DO-214AA) surface-mount package, the SMBJ3V3CA features excellent clamping capability, glass-passivated chip junction, and ultra-fast response time. Its 600W peak pulse power rating, 50A peak pulse current, and AEC-Q101 qualification availability make it suitable for demanding industrial, automotive, and communication applications.

This diode is ideal for safeguarding microcontrollers, ICs, MOSFETs, communication lines, sensor inputs, and other delicate 3.3V electronics from damaging transient events.
