DT-Triac™ Technology Platform

The IXYS/Littelfuse DT-Triac™ is designed for line-frequency applications and three-quadrant operation, namely quadrants I to III. Target applications are solid-state relays, soft-start AC motor control, DC motor control, HVAC systems, UPS, AC power control, input power control for SMPSs, lighting and heater controls.

Triacs are known as best-in-class for AC power control, providing better power density in numerous power system applications. However, traditional triacs have been limited to lower currents and voltages, and low dV/dT and di/dt ratings.

The CLA80MT1200NHB is a TO-247 AC-controller product with 1200 volt, 80 A using the new DT-Triac technology. Furthermore, an isolated version is introduced in an ISO247™ housing, named CLA80MT1200NHR.

For surface mounted applications, the TO-263ABHV - D2Pak without middle pin for higher creepage distance - provides a 30 and a 40 A version: CLA30MT1200NPZ and CLA40MT1200NPZ. Both parts are also available as TO-220 versions (...NPB).
