Overview

The STGAP3S3STR is a single-channel, galvanically isolated gate driver featuring capacitive coupling technology for 5700Vrms isolation. It provides up to 3A output current and 200V/ns CMTI, making it highly robust for driving power MOSFETs, SiC, and IGBTs in high-voltage environments. The device includes integrated protection features such as desaturation detection, Miller clamping, and adjustable soft turn-off.

Why Choose This Part

This driver offers exceptional noise immunity with a 200V/ns CMTI rating and a wide output supply range up to 32V. Integrated safety features like Miller clamping and negative gate driving capability simplify circuit design while improving reliability in high-dV/dt switching applications.

Applications

High-Voltage Inverters
Driving SiC or IGBT power modules in industrial motor drives and renewable energy inverters requiring 5.7kVrms isolation.
EV Traction Inverters
Utilizing high CMTI (200V/ns) and integrated desaturation protection to manage power switching in electric vehicle drivetrains.
Switch-Mode Power Supplies (SMPS)
