High temperature TRIAC for IoT thermal management

High temperature TRIAC for IoT thermal management

Available in compact, surface-mount packages, these components are the industry’s first TRIAC (bidirectional triode thyristor) with such a high maximum temperature that are available in ratings of 4A, 6A, and 8A. This combination of space-saving packaging, high temperature capabilities and choice of current ratings makes them well-suited for Internet of Things (IoT) applications that require compact design but don’t involve continuous high currents. The deviecs are suitale for designs such as smart doorbells, thermostats, ceiling fans/lights and door locks, as well as 110VAC control such as smart ceiling lights, fans and LED flood lights.

The sensitive-type components guarantee low current gate control in Quadrants I and IV to interface directly with digital control circuitry. Standard-type components normally operate in Quadrants I and III and are triggered from the AC line. Alternistor-type components only operate in Quadrants I, II, and III, are triggered from the AC line, and are used in circuits requiring high dv/dt capability. With a maximum junction temperature of 150 °C, the devices help designers address thermal management issues due to limited or no heat sinking by providing a larger thermal design margin. The high surge capabilities simplify handling cold in-rush currents in heater or motor control applications.

“The combination of the robust clip-attach assembly design and the maximum operating junction temperature ensures the high surge capability needed to withstand short-duration overload conditions,” said Koichiro Yoshimoto, Business Development Manager, Semiconductor Business Unit at Littelfuse. “By offering a choice of current ratings in small, surface-mount packages, these components allow designers to minimize board sizes for low power applications such as LED lighting, solenoid drives and motor drives.“

The High-Temperature Sensitive, Standard and Alternistor TRIAC are available in TO-251 (VPAK) or TO-252 (DPAK) packages in tube pack (75 per tube) in quantities of 750 or in embossed carriers in quantities of 2,500.
