25 A standard triac for mains-voltage AC switching
It is designed for AC load switching in applications such as motor speed controls, industrial heating, lighting dimmers, and solid-state relays where a robust, general-purpose triac is needed.
Gate drive and surge robustness
With a maximum gate trigger current of 50 mA and a maximum gate trigger voltage of 1.3 V, this standard triac requires a driver stage capable of sourcing that current — a microcontroller GPIO or logic gate alone will not trigger it reliably. 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.
