It belongs to the Snubberless™ series, which means the device is designed to commutate inductive loads (motors, solenoids, transformers) without requiring an external RC snubber network — the die itself handles the dV/dt stress during turn-off. The 50 mA maximum gate trigger current (Igt) and 1.3 V maximum gate trigger voltage (Vgt) are standard for this current class and compatible with common optocoupler or logic-level drive circuits. The 160 A / 168 A non-repetitive surge current rating (Itsm at 50/60 Hz) gives headroom for inrush from lamp filaments or motor start. The 400 V off-state voltage provides adequate margin for 120 VAC and 240 VAC mains lines, including the typical 10% overvoltage transients seen in industrial zones. The BTA16-400BWRG is marked obsolete by STMicroelectronics. Date-code spreads vary by lot — we quote each lot individually against an RFQ, confirming original packaging and condition.","metaTitle":"ST BTA16-400BWRG Snubberless Triac, 16 A, 400 V, TO-220","metaDescription":"ST BTA16-400BWRG Snubberless™ Alternistor triac: 16 A RMS, 400 V off-state, 50 mA Igt, TO-220, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"Snubberless™","Package":"Tube","Triac Type":"Alternistor - Snubberless","Configuration":"Single","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BTA16","Voltage - Off State":"400 V","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"TO-220","Current - Hold (Ih) (Max)":"50 mA","Current - Gate Trigger (Igt) (Max)":"50 mA","Voltage - Gate Trigger (Vgt) (Max)":"1.3 V","Current - On State (It (RMS)) (Max)":"16 A","Current - Non Rep.
