Gate trigger current is 35 mA max with a 1.3 V max trigger voltage, compatible with standard MCU I/O via a driver transistor. ## 16 A RMS — heatsink and derating decisions The 16 A RMS on-state current is the continuous load rating. In practice, a TO-220 in free air at 25°C ambient will need a heatsink to stay below the 125°C junction limit at full current. The non-repetitive surge rating of 160 A at 50 Hz and 168 A at 60 Hz covers motor start and capacitor-charging inrush — that figure is what the fuse or breaker must be sized below to avoid nuisance trips. The 35 mA holding current is typical for a 16 A triac; it ensures the device latches on cleanly at low load currents. STMicroelectronics no longer manufactures this specific order code. If your design can accept a pin-compatible alternative, the wider BTB16 family (same TO-220 footprint, same 700 V / 16 A ratings) includes active variants — but the CWRG suffix (Snubberless™, 35 mA Igt) may differ in trigger sensitivity or commutation grade.","metaTitle":"ST BTB16-700CWRG Snubberless™ Triac, 700 V, 16 A, TO-220","metaDescription":"STMicroelectronics BTB16-700CWRG Snubberless™ triac, 700 V off-state, 16 A RMS, TO-220.

STMicroelectronics has discontinued production. No direct replacement order code is provided in the lifecycle record. For new designs, consider an active Snubberless™ triac in the BTB16 family with the same 700 V, 16 A ratings, but verify trigger current and package suffix compatibility."},{"question":"Is the BTB16-700CWRG compatible with the BTA16?","answer":"The BTB16-700CWRG and BTA16 are both 16 A triacs from STMicroelectronics, often in the same TO-220 footprint. The key difference is the Snubberless™ construction of the BTB16, which allows inductive-load commutation without an external snubber. The BTA16 typically requires a snubber for inductive loads. Pin compatibility depends on the specific BTA16 suffix — verify the datasheet pinout for your exact BTA16 variant before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BTB16-700CWRG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BTB16-700CWRG when reusing this data.
