That 25 A figure is the continuous load current the device can switch — think motor drives, resistive heating banks, or solid-state relay outputs in industrial controllers. The alternistor structure means it commutates inductive loads (motors, solenoids, transformers) without an external RC snubber, which saves two passives and a chunk of board area per phase. ## Surge handling and gate drive Non-repetitive surge current is 250 A at 50 Hz and 260 A at 60 Hz — that covers inrush from capacitive loads or motor start-up without fusing the die. Gate trigger current is 35 mA max, gate trigger voltage 1.3 V max, so a standard logic-level driver or a simple transistor circuit can fire it. Hold current is 50 mA max, which means the triac stays latched once triggered until the load current drops below that threshold — relevant for low-current loads like small fans where the hold current might not be met. ROHS3 compliant, no lead in the finish. No official second-source or direct replacement is listed, but the T1235-600G is a surface-mount Snubberless alternistor (12 A, 600 V) if the design can move to SMT and a lower current tier.","metaTitle":"STMicroelectronics BTB24-600CWRG Triac Alternistor","metaDescription":"STMicroelectronics BTB24-600CWRG Snubberless alternistor triac, 600V off-state, 25A RMS on-state, TO-220-3.
