SMBJ51CA 51V Bidirectional TVS Diode – SMB (DO-214AA)

Product Description:
The SMBJ51CA TVS Diode is a high-performance bidirectional transient voltage suppressor designed to protect sensitive 51V electronic circuits from damaging voltage spikes. With a reverse stand-off voltage of 51V, a breakdown voltage up to 62.7V, and a clamping voltage of 82.4V, it provides robust and reliable surge protection for industrial, automotive, and communication applications.

Built in a compact SMB (DO-214AA) package, this diode offers excellent clamping performance, ultra-fast response time (<1 ps), and a peak pulse current rating of 7.3A, ensuring stable protection in high-energy transient environments. It supports high-temperature soldering and is ideal for automated manufacturing processes.

The SMBJ51CA is suitable for safeguarding ICs, MOSFETs, sensor lines, and power rails in systems exposed to inductive load switching, lightning surges, and ESD events.
