SMBJ58A Alternative / Equivalent / Replacement

2. Product Overview

The SMBJ series is one of the most widely used surface-mount TVS diode families. It covers breakdown voltages from 5.0V to 188V in the DO-214AA (SMB) package. Each part delivers 600W peak pulse power for a broad range of surge protection applications.

The SMBJ58A is a 600W rated variant for protecting 48V DC power rails in telecom and industrial equipment. Its stand-off voltage of 58V lets it sit across a 48V to 58V supply line without conducting under normal conditions. It clamps the surge to a maximum of 93.6V.

YINT produces the full SMBJ series from 5.0V through 188V. This complete voltage coverage lets customers source all DO-214AA TVS needs from one manufacturing partner, simplifying supply chain management.
