High-temperature sensitive TRIACs


STMicroelectronics has introduced TRIACs with 10mA gate sensitivity to be specified for operation up to 150 degrees C without derating. The devices introduced are the T410H rated for maximum current of 4A, the 6A T610H, 8A T810H and 10A T1010H. Their gate current of 10mA allows direct logic-level switching of the TRIAC, which saves component count and reduces the size and cost of the power supply. In addition, the low gate current maintains high dynamic performance, maintaining specified minimal commutation and 75V/microsecond noise immunity at up to 150 degrees C.

The devices are dedicated to control of AC loads such as electric heaters, inductive heating equipment, medium-power motors, and other small appliances. All devices are rated up to 600V, for reliable operation in mains-powered systems. They are available in the industry-standard TO-220AB through-hole package, and the T810H and T1010H will also be introduced in the surface-mount D2PAK package. The T410H, T610H, T810H and T1010H will be priced from $0.40 in quantities of 10,000 pieces, and are in volume production.
