High commutation performance Doeshare DT8T35I-BH TRIAC suitable for LED dimming and solenoid drivers
Product Overview
The DT8T High Temperature Series TRIACs are silicon bidirectional thyristors designed for high commutation performance in the third quadrant without the need for a snubber circuit. These devices offer reliable control for general-purpose AC switching applications and can be triggered by phase angle or on/off methods. Key features include a passivated die for enhanced reliability, three-quadrant triggering capability, high voltage ratings (over 800V VDRM/VRRM), and operation up to 150C. They are constructed with a "Green" molding compound compliant with UL 94V-0 flammability classification and are RoHS II 2015/863/EU compliant. Applications include motor, fan, and pump control, solenoid drivers, LED dimming, logic control, and inrush current limiting circuits.
