Triacs allow high junction temperatures

14 May 2008 Power Electronics / Power Management

STMicroelectronics has announced a new series of high-temperature triacs, which maintain full specified performance up to a junction temperature of 150°C, and which deliver outstanding turn-off capability - ideal for appliance motor-control applications, in particular - at their maximum temperature.

The HiTj series devices are ideal for use in universal motor-control applications, such as vacuum cleaners, washing-machine drum motors, and industrial drives; in hot environments such as cookers, ovens, kitchen hobs and coffee machines; and for achieving higher power density on PCBs, for heater and high-power motor control. They can also replace conventional triacs in closed environments with high ambient temperature.

The HiTj TRIAC series is produced in TO-220AB, TO-220AB insulated (ceramic), and in D2PAK surface-mount packages, for maximum versatility. They are all 600 V devices, with current ratings of 8, 10, 12, 16 and 20 A. The sensitivity range is 35 mA to 50 mA.
