55PT

SEMICONDUCTOR 55PT Series RRooHHSS Stansard SCRs, 55A Main Features Symbol IT(RMS) VDRM/VRRM IGT Value 55 600 to 1600 80 Unit A V mA DESCRIPTION The 55PT series of silicon controlled rectifiers are high performance glass passivated technology, and are suitable for general purpose applications, where power handling and power dissipation are critical, such as solid state relay, welding equipment and high power motor control. Base on a clip assembly technology, they offer a superior performance in surge current capabilities. Thanks to their internal ceramic pad, they provide high voltage insulation(2500VRMS).
