Non-repetitive surge current is 120 A at 50 Hz and 126 A at 60 Hz — enough to handle inrush from motor starts or cold-filament lamp strikes without exceeding the die's thermal capacity. Holding current (Ih) is 15 mA maximum. Below this load current the triac will commutate off at zero-cross; designs driving very light loads — below 15 mA — may need a dummy resistor to guarantee latching. The BTA12 base number is a long-running ST power-logic family; replacement risk is low for the foreseeable production horizon.","metaTitle":"ST BTA12-600SWRG Sensitive Gate Triac, 600V 12A TO-220","metaDescription":"STMicroelectronics BTA12-600SWRG logic-level sensitive gate triac. 600V off-state, 12A RMS on-state, 10mA Igt.
