It handles non-repetitive surge currents of 250 A at 50 Hz and 260 A at 60 Hz, giving headroom for motor-start and capacitor-charging transients. ## Gate drive and conduction losses Maximum gate trigger current is 40 mA at 1.5 V — a standard logic-level driver or a simple resistor from a 5 V supply will fire it. Once latched, the holding current of 50 mA minimum keeps the SCR conducting; below that threshold the device turns off. On-state voltage drop is 1.6 V max at rated current, so at 16 A average the conduction loss is about 26 W — the TO-220 tab needs a heatsink sized for that dissipation in your airflow. ## Off-state leakage and blocking performance Maximum off-state leakage is 5 µA at rated 200 V — negligible for most designs, but worth noting if the load is a high-impedance circuit where microamps matter. The standard recovery type means turn-off time is not optimised for high-frequency switching; this part is for line-frequency (50/60 Hz) phase control, not for PWM or fast commutation.","metaTitle":"STMicroelectronics TYN225RG SCR, 25 A RMS, 200 V, TO-220","metaDescription":"Standard recovery SCR, 16 A average / 25 A RMS on-state, 200 V off-state, 250 A surge.
