SMBJ75CA Description

Short technical summary and product information.

The SMBJ75CA is a bidirectional TVS diode from Littelfuse Inc., part of the SMBJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. Key specifications include a reverse standoff voltage of 75V, a maximum clamping voltage of 121V, and a peak pulse power rating of 600W at 10/1000µs waveform. The device offers fast response time typically less than 1ps and ESD protection up to 30kV air and contact per IEC-61000-4-2. It is housed in a surface mount DO-214AA (SMB) package with matte tin lead-free plating. The SMBJ75CA is RoHS compliant, halogen free, and meets MSL Level 1. Typical applications include protection of I/O interfaces, VCC bus, and vulnerable circuits in telecom, computer, industrial, and consumer electronics.
