The 15 mA max holding current means the triac stays latched once triggered as long as the load current stays above that threshold; below 15 mA the device may drop out, so a bleeder resistor across the load may be needed for very low-current loads. ## Surge capability and thermal margin Non-repetitive surge current is rated 60 A at 50 Hz and 63 A at 60 Hz — this handles the inrush from a motor start, a lamp cold filament, or a capacitor bank without commutating the triac into conduction during the surge event. ## Package and compliance The TO-220 Full Pack (TO-220FPAB) is a through-hole package with the metal tab fully encapsulated — no external isolation washer is needed when mounting to a chassis or heatsink, which simplifies assembly and reduces BOM count.","metaTitle":"STMicroelectronics T810T-8FP Triac, 800 V, 8 A","metaDescription":"T810T-8FP sensitive-gate triac from STMicroelectronics: 800 V off-state, 8 A RMS, 10 mA Igt.
