SMBJ48CA 48V Bidirectional TVS Diode – SMB (DO-214AA)

Product Description:
The SMBJ48CA TVS Diode is a robust bidirectional transient voltage suppressor designed to protect sensitive 48V electronic systems from voltage spikes caused by lightning, inductive load switching, and electrostatic discharge. With a reverse stand-off voltage of 48V, a maximum breakdown voltage of 58.9V, and a clamping voltage of 77.4V, it ensures highly reliable surge suppression in demanding environments.

This diode delivers a peak pulse current of 7.8A and offers excellent clamping performance with an ultra-fast response time of less than 1 ps. Its low-profile SMB (DO-214AA) package supports automated assembly and high-temperature soldering, making it a reliable and durable choice for industrial, telecom, automotive, and embedded electronics.
