Product Introduction

Overview

The SM6T12A is a Transient Voltage Suppressor (TVS) diode produced by STMicroelectronics. This component is designed to protect sensitive electronic equipment from electrostatic discharges (ESD) and electrical overstress (EOS) according to various international standards, including IEC 61000-4-2 and MIL STD 883. The SM6T12A is part of the SM6T series, which offers a range of stand-off voltages and is packaged in the SMB format. This device is particularly suited for high-end equipment and Switch-Mode Power Supplies (SMPS) where low leakage current and high junction temperature are critical for reliability and stability.
