Overview
The SM6T27A is a Transient Voltage Suppressor (TVS) diode produced by STMicroelectronics. It is part of the SM6T series, designed to protect sensitive equipment against electrostatic discharges (ESD) and electrical overstress (EOS) according to IEC 61000-4-2, IEC 61000-4-4, and MIL STD 883 standards. This unidirectional TVS diode is packaged in an SMB (Small Outline Molded) package, making it suitable for high-end equipment and Switch-Mode Power Supplies (SMPS) where low leakage current and high junction temperature are critical.
