SMBJ85CA 85V Bidirectional TVS Diode – SMB (DO-214AA)

Product Description:
The SMBJ85CA TVS Diode is a robust bidirectional transient voltage suppressor designed for protecting 85V-powered electronic circuits from harmful voltage spikes caused by lightning surges, inductive load switching, and ESD events. With a reverse stand-off voltage of 85V, a maximum breakdown voltage of 104V, and a clamping voltage of 137V, this diode delivers reliable surge suppression for sensitive components.

Housed in a compact SMB (DO-214AA) SMD package, the SMBJ85CA provides excellent clamping capability, fast response time (<1 ps), and high-temperature soldering endurance (260°C for 10 seconds). This ensures durability and compatibility with automated PCB assembly processes.

The diode supports a peak pulse current of 4.4A, making it suitable for industrial equipment, automotive electronics, telecom systems, signal line protection, and high-reliability power systems.
