Teccor® brand Thyristors 8 Amp Alternistor Quadrac for LED dimmer applications Q6008LTH1LED Series RoHS Description The Quadrac is an internally triggered Triac designed for AC switching and phase control applications. It is a Triac and DIAC in a single package, which saves user expense by eliminating the need for separate Triac and DIAC components. Q6008LTH1LED series is designed to meet low load current characteristics typical in LED lighting applications. By keeping holding current at 6mA maximum, this Quadrac series is characterized and specified to perform best with LED loads. The Q6008LTH1LED series is best suited for LED dimming controls to obtain the lowest levels of light output with a minimum probability of flickering. Agency Approval Q6008LTH1LED series is offered in the industry standard TO-220AB package with an isolated mounting tab that makes it best suited for adding an external heat sink.

Other ways to ensure long life for a power discrete Lead Bend MIL-STD-750: Method 2036, Condition E semiconductor are proper heat sinking and selection of voltage ratings for worst case conditions. Overheating, overvoltage (including dv/dt), and surge currents are the main killers of semiconductors.
