It is designed for line-frequency phase-control applications such as motor speed controllers, light dimmers, and input rectifier crowbars in power supplies. The 25 mA maximum gate trigger current (Igt) and 1.5 V maximum gate trigger voltage (Vgt) set the drive requirement from the control IC or transistor. A standard optocoupler or small-signal transistor can fire it directly, but the 40 mA maximum holding current (Ih) means the load must draw at least 40 mA to keep the SCR latched once triggered — below that, the device drops out at the zero-crossing. On-state voltage drop is 1.6 V max at rated current (Vtm), which sets the conduction loss at roughly 16 W for a 10 A average load — heatsink sizing needs to handle that dissipation in a TO-220 tab. ## Surge rating and temperature range Non-repetitive surge current is 160 A at 50 Hz and 167 A at 60 Hz (Itsm) — this is the one-cycle fault withstand for fuse coordination. Off-state leakage is 5 µA max at rated voltage, which is negligible for standby power budgets. A pin-compatible replacement within the same TO-220 SCR family would need to match the 400 V / 16 A RMS rating and the 25 mA gate trigger threshold — any substitution should be verified against the original BOM's thermal and surge requirements.","metaTitle":"STMicroelectronics TYN416RG SCR, 400V 16A RMS, TO-220","metaDescription":"Standard recovery SCR, 400 V off-state, 16 A RMS on-state, 25 mA Igt.
