The 700 V off-state rating gives comfortable margin for 230 VAC or 277 VAC mains lines, even with the line transients common in industrial environments. Surge capability is 160 A at 50 Hz and 168 A at 60 Hz non-repetitive — enough for lamp inrush or motor start events. ## Temperature range and package — where it fits The TO-220-3 through-hole package mounts to a heatsink with a single screw — standard for this current class. Gate trigger current is 50 mA max, gate trigger voltage 1.3 V max, and hold current 50 mA max, so a simple microcontroller GPIO driving an optocoupler or a small bipolar transistor can fire it. ## Pin-compatible alternatives in the family The BTA16-700BRG is the same base product (BTA16) in the same TO-220-3 package but a standard (non-Snubberless) triac. If your design already includes an external snubber, that part is a drop-in replacement. For a Snubberless replacement, verify the gate trigger and hold current specs against your drive circuit.","metaTitle":"ST BTA16-700BWRG Snubberless Triac, 16A 700V TO-220","metaDescription":"ST BTA16-700BWRG Snubberless Alternistor triac, 16A RMS, 700V off-state, TO-220-3, -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":"700 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.

It is pin-compatible and can replace the BTA16-700BWRG if your circuit already includes an external snubber network.
