VS-50RIA series medium power phase control thyristors providing single-SCR circuit configuration in a TO-65 (TO-208AC) package. Key ratings include IT(AV)=50 A, IT(RMS)=80 A, and ITSM up to 1490 A depending on test frequency and conditions, with VDRM/VRRM range from 100 V to 1200 V. Operating junction temperature spans -40 °C to +125 °C. Electrical and switching parameters cover typical VTM=1.60 V, IGT=100 mA, td and tq values, and controlled dI/dt and dV/dt options. Typical uses include phase control converters, lighting circuits, battery charging, and regulated power supplies with temperature or speed control.
