Littelfuse QJxx10 High Temp Alternistor Standard Triacs

Mouser Electronics recommends: Littelfuse QJxx10 High-Temperature Alternistor/Standard (High Communication) Triacs are offered in TO-220AB, TO-220 isolated, and TO-263 packages with a +150°C maximum junction temperature and 120A ITSM at 60Hz. These devices enable easier thermal management and higher surge handling capability in AC power control applications such as heater control, motor speed control, lighting controls, and static switching relays. The alternistor version TRIACs (no snubber required) operate in quadrant I, II, and III, while offering high performance in applications requiring high commutation capability. The standard type devices normally operate in Quadrants I and III triggered from the AC line.
