Available in through-hole or surface mount packages, these Triac series are suitable for general purpose mains power ac switching.
These 20 A Triacs provide a very high switching capability up to junction temperatures of 150 °C.
The heatsink can be reduced, compared to traditional Triacs, according to the high performance at given junction temperatures.
By using an internal ceramic pad, the TO-220AB insulated version provide voltage insulation (rated at 2500 VRMS).
The surface mount D²PAK package enables compact SMD based designs for automated manufacturing.Key Features
