TRIACs withstanding 150 Deg C temperature with low gate sensitivity of 10 mA

ST Microelectronics has released to market new TRIACs with 10mA gate sensitivity and withstanding a ambient temp of 150 degrees C without derating. The targeted applications are heaters, motors and other small appliances.

The new TRIAC components are T410H rated for maximum current of 4Amps, the 6Amps T610H, 8Amps T810H and 10Amps T1010H. Their low gate current of 10mA allows direct logic-level switching of the TRIAC. 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. This high maximum junction temperature (Tj) allows designers to reduce or remove heatsinks in cost-sensitive designs, increase power density, and enhance reliability at high ambient temperatures.

The new TRIACs are ideal for 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 to operate from mains-powered systems.

All devices 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.
