SMBJ70CA 70V Bidirectional TVS Diode – SMB (DO-214AA)

Product Description:
The SMBJ70CA TVS Diode is a high-performance bidirectional transient voltage suppressor designed to protect 70V electronic systems from damaging voltage spikes caused by lightning surges, inductive load switching, and ESD events. With a reverse stand-off voltage of 70V, a breakdown voltage up to 86V, and a clamping voltage of 113V, this diode ensures strong surge protection for sensitive ICs, MOSFETs, signal interfaces, and high-voltage power lines.

Encased in a compact SMB (DO-214AA) surface-mount package, the SMBJ70CA offers excellent clamping performance, ultra-fast response time (<1 ps), and high-temperature soldering compatibility (260°C / 10s). Its low-profile package and built-in strain relief make it ideal for automated assembly and long-term operation in demanding environments.

With a peak pulse current capability of 5.3A, this diode is suitable for industrial, automotive, telecom, and power system applications requiring reliable transient suppression.
