SMCJ58A Alternative / Equivalent / Replacement - 1500W TVS Diode 58V SMC | YINT

Need a SMCJ58A alternative, equivalent, or replacement for your design? YINT Electronics provides a compatible SMCJ58A substitute that aligns with the specifications of Littelfuse, Vishay, and ON Semiconductor components, ensuring reliable protection for 48V and 58V DC power rail applications.

1. Product Overview

The SMCJ58A is a 1500W unidirectional TVS diode that protects 48V and 58V DC power rails from voltage transients caused by lightning, ESD, and inductive load switching. It has a stand-off voltage of 58V, breakdown range of 64.4V to 71.2V, and clamping voltage of 93.6V. The device responds in less than 1 nanosecond and delivers 16.1A peak pulse current in the SMC DO-214AB package.

Engineers looking for a SMCJ58A replacement for Littelfuse, Vishay, ON Semiconductor, Diodes Incorporated, STMicroelectronics, Bourns, or Taiwan Semiconductor can confidently specify YINT's SMCJ58A. It operates from -55C to +150C and is suitable for 48V systems in automotive electronics, telecom equipment, and power conversion.
