The 10 mA maximum gate trigger current lets a microcontroller I/O or optocoupler fire it directly, eliminating a driver transistor from the BOM. Intended for AC load switching in industrial and appliance controls — motor starters, heater banks, lighting ballasts, and solid-state relays — where the 125°C junction temperature rating covers the thermal environment of a sealed enclosure or adjacent heatsink. ## Package and mounting — TO-220 thermal path The TO-220-3 package (supplier device package TO-220) is a through-hole tab-mount design. The metal tab is the collector/drain thermal path — bolt it to a heatsink with thermal compound for any load above a few amps. The 16 A RMS rating assumes adequate heatsinking; at full current in free air the die will exceed the 125°C junction limit without one.","metaTitle":"STMicroelectronics BTA16-800SWRG Triac, 800V 16A","metaDescription":"ST BTA16-800SWRG sensitive-gate triac, 800V off-state, 16A RMS on-state, 10mA Igt.

That qualifies it as a sensitive-gate triac, drivable directly from logic-level outputs."},{"question":"Can BTA16-800SWRG be used for AC dimming?","answer":"Yes, the sensitive-gate characteristic (10 mA Igt) and 16 A RMS rating make it suitable for phase-control AC dimming of resistive and inductive loads like incandescent lamps, heaters, and small motors, provided the load current stays within the 16 A rating and adequate heatsinking is used."},{"question":"What are the alternatives to BTA16-800SWRG?","answer":"The closest functional siblings in the same sensitive-gate family are the BTA08-600TWRG and BTA08-600SWRG, both rated for 600 V off-state and 8 A RMS on-state. They are not pin-for-pin replacements — the voltage and current ratings differ — but share the same TO-220 package and logic-level gate drive."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BTA16-800SWRG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BTA16-800SWRG when reusing this data.
