It is a single-configuration device intended for AC load switching in industrial and appliance applications — motor speed controls, heater drives, lighting dimmers, and solid-state relays where the load stays within the 6 A continuous envelope. ## Gate drive and trigger thresholds The gate trigger current (Igt) is 25 mA maximum, with a gate trigger voltage (Vgt) of 1.3 V maximum. That 25 mA Igt is the number to size the drive circuit around — an MCU GPIO driving a transistor or an optocoupler output needs to source at least that much current into the gate to guarantee turn-on across temperature. The holding current (Ih) is also 25 mA maximum, meaning the load current must stay above that level to keep the TRIAC latched once triggered; below that, the device drops out at zero-cross. For low-current loads like a small fan or a relay coil, verify the load current exceeds Ih or add a dummy load. ## Surge handling and thermal budget Non-repetitive surge current (Itsm) is rated at 60 A for 50 Hz and 63 A for 60 Hz — this is the single-cycle peak the die can survive during a fault or inrush event like a lamp cold-start or motor start. The 6 A RMS on-state rating is the continuous conduction limit; for a 6 A resistive load at 230 V AC, expect junction rise that requires a heatsink.","metaTitle":"ST BTA06-400CRG TRIAC, 400 V 6 A TO-220-3, Active","metaDescription":"ST BTA06-400CRG standard TRIAC, 400 V off-state, 6 A RMS on-state, 25 mA Igt, TO-220-3 through-hole, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Triac Type":"Standard","Configuration":"Single","Mounting Type":"Through Hole","Package / Case":"TO-220-3","lifecycle_stage":"eol_hot","Voltage - Off State":"400 V","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"TO-220","Current - Hold (Ih) (Max)":"25 mA","Current - Gate Trigger (Igt) (Max)":"25 mA","Voltage - Gate Trigger (Vgt) (Max)":"1.3 V","Current - On State (It (RMS)) (Max)":"6 A","Current - Non Rep.
