It is a single-configuration device with a maximum gate trigger current of 50 mA and a gate trigger voltage of 1.3 V. The hold current is also 50 mA, typical for a triac of this current class. The non-repetitive surge current rating is 160 A at 50 Hz and 168 A at 60 Hz, giving it headroom for motor or lamp inrush. For new designs or replacement needs, the BTA16-600BRG is a common cross-shop candidate — it shares the same package, pinout, and trigger characteristics but offers a 600 V off-state rating instead of 400 V. Because this part is obsolete, the primary sourcing channel is independent distribution. ## Package and mounting — through-hole TO-220 The BTA16-400BRG comes in a TO-220-3 through-hole package, shipped in Tube form. The through-hole mounting suits point-to-point wiring on perfboard or PCB soldering with adequate copper area for thermal dissipation.","metaTitle":"ST BTA16-400BRG Triac, 16 A RMS, 400 V, TO-220-3","metaDescription":"STMicroelectronics BTA16-400BRG standard triac, 16 A RMS on-state, 400 V off-state, TO-220-3 through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tube","Triac Type":"Standard","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.
