The 80 mA maximum holding current sets the minimum load current needed to keep the triac latched on after the gate pulse is removed; below that level the device will commutate off at the next zero-cross. The non-repetitive surge current rating of 250 A at 50 Hz and 260 A at 60 Hz gives the BTB24-600BRG the headroom to handle motor inrush, lamp cold-filament surges, and capacitor charging events without failing. This surge capability, combined with the 25 A continuous rating, makes it a fit for applications where the load has a high peak-to-RMS ratio.","metaTitle":"STMicroelectronics BTB24-600BRG TRIAC, 600 V, 25 A, TO-220","metaDescription":"Standard TRIAC, 600 V off-state, 25 A RMS on-state, 50 mA gate trigger.
