High commutation performance silicon bidirectional thyristors Doeshare DT1T5G-B for motor fan and digital control

Product Overview

The DT1T Series TRIACs are sensitive gate, silicon bidirectional thyristors designed for high commutation performance without the need for a snubber circuit. These devices are compatible with logic-level inputs, making them suitable for a wide range of applications including general purpose motor control, small loads in fan control, solenoid drivers, LED dimming, and digital control drivers. They feature passivated dice for enhanced reliability and uniformity, and are available in TO-92 and SOT-223 packages. The series offers over 1000V/800V VDRM/VRRM ratings and low level triggering and holding characteristics.
