SMBJ90CA 90V Bidirectional TVS Diode – SMB (DO-214AA)

Product Description:
The SMBJ90CA TVS Diode is a high-reliability bidirectional transient voltage suppressor designed to protect 90V electronic systems from damaging voltage spikes caused by lightning surges, inductive load switching, and ESD events. Offering a reverse stand-off voltage of 90V, a breakdown voltage up to 111V, and a clamping voltage of 146V, this diode delivers strong and dependable surge suppression for sensitive power and signal lines.

Built in a compact SMB (DO-214AA) surface-mount package, the SMBJ90CA provides excellent clamping performance, ultra-fast response time (<1 ps), and high-temperature soldering resilience (260°C / 10 seconds), making it ideal for modern automated PCB assembly.

With a peak pulse current rating of 4.1A, this diode ensures stable and robust protection in industrial equipment, telecom circuits, automotive systems, and high-voltage control electronics.
