It switches AC loads — heaters, small motors, lighting — where the gate is driven directly from a logic-level source like a microcontroller or a low-power sensor output. ## Gate trigger and hold current — the bench-fit numbers The holding current (Ih) is 10 mA max, meaning the TRIAC stays latched once triggered as long as the load current stays above that threshold; below it the device turns off at the next zero-crossing. ## Surge current and thermal robustness Non-repetitive surge current (Itsm) is rated 80 A at 50 Hz and 84 A at 60 Hz — this covers the inrush from a cold incandescent lamp filament or a capacitor-input power supply.","metaTitle":"STMicro BTB08-600TWRG TRIAC, Sensitive Gate 600V 8A TO-220","metaDescription":"BTB08-600TWRG from STMicroelectronics: 8A RMS, 600V off-state, sensitive-gate TRIAC in TO-220.
