T2550H Snubberless™ high temperature 25 A Triacs Main features A2 Symbol Value Unit IT(RMS) 25 A VDRM/VRRM 600 V IGT (Q1) 50 mA G A1 A2 Description A1 A2 G Specifically designed for use in high temperature environment (found in hot appliances such as cookers, ovens, hobs, electric heaters, coffee machines...), the new 25 A T2550H triacs provide an enhanced performance in terms of power loss and thermal dissipation. This allows for optimization of the heatsinking dimensioning, leading to space and cost effectivness when compared to electro-mechanical solutions. T0-220AB T2550H-600TRG Order code Based on ST snubberless technology, they offer high commutation switching capabilities and high noise immunity levels. And, thanks to their clip assembly technique, they provide a superior performance in surge current handling. Table 1.
