T2550H High temperature 25 A SnubberlessTM TRIAC Features A2 Medium current TRIAC 150 C max. Tj turn-off commutation Low thermal resistance with clip bonding Very high 3 quadrant commutation capability RoHS (2002/95/EC) compliant package G A1 A2 Applications A1 A2 G Specifically designed for use in high temperature environment (found in hot appliances such as cookers, ovens, hobs, electric heaters, coffee machines). T0-220AB T2550H-600TRG Description This 25 A T2550H TRIAC provides an enhanced performance in terms of reduced power loss and thermal dissipation. This allows for the optimization of the heatsinking dimensions, leading to space and cost effectivness when compared to electro-mechanical solutions. Table 1. Based on ST snubberless technology, the T2550H offers high commutation switching capabilities and high noise immunity levels. Thanks to the clip assembly technique, it provides a superior performance in surge current handling.
