The 16 A average current rating supports continuous conduction in phase-control circuits like motor drives, soft starters, and industrial power supplies. Gate trigger current is 40 mA max, which is a standard level for direct drive from a microcontroller I/O through a series resistor — no separate driver IC needed for most designs. ## Thermal and surge capability Non-repetitive surge current is 250 A at 50 Hz and 260 A at 60 Hz — this surge rating handles inrush from capacitive loads or motor start events. Off-state leakage is 5 µA max, and on-state voltage is 1.6 V max at rated current, which sets the conduction loss for heatsink sizing. The metal tab is the anode connection — electrical isolation from the heatsink is required unless the heatsink is at anode potential.","metaTitle":"STMicroelectronics TYN1225RG SCR, 1.2 kV 25 A TO-220-3","metaDescription":"STMicroelectronics TYN1225RG standard recovery SCR, 1.2 kV off-state, 25 A RMS, 40 mA Igt, TO-220-3.
