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.
