It belongs to the Snubberless™ series, which means the die is structured to handle high dv/dt without an external RC snubber — a real BOM saver when the load is inductive (motor, solenoid, transformer) and the board is tight on passives. The 35 mA gate trigger current (Igt) and 1.3 V gate trigger voltage (Vgt) are standard for a 16 A class triac, compatible with common MCU-driven optocoupler or logic-level trigger circuits. The 35 mA holding current (Ih) ensures the device latches on once triggered and does not drop out on load current ripple near zero-cross. The 160 A / 168 A non-repetitive surge current (50/60 Hz) handles cold-start inrush from incandescent lamps or capacitive loads without fusing the die. ## Snubberless™ structure — what it saves on the BOM A conventional triac driving an inductive load needs a snubber network to limit dv/dt and prevent false turn-on. The Snubberless alternistor structure achieves high dv/dt without that network. The trade-off is a slightly higher gate trigger current (35 mA max) compared to a sensitive-gate triac like the BTA06-600SRG (which triggers at lower Igt). If the drive circuit is a low-current optocoupler, verify the opto can source 35 mA peak. For MCU-driven circuits with a transistor buffer, it is not a constraint. ## TO-220-3 — mounting and thermal management The TO-220-3 package (supplier device package TO-220) is a through-hole tab-mount. The metal tab is the MT2 terminal and the primary thermal path. For 16 A RMS continuous, a heatsink is mandatory — the junction-to-case thermal resistance will dictate the heatsink size. The tab is electrically live, so an insulating washer and thermal compound are needed if the heatsink is grounded. ## Active lifecycle — no obsolescence contingency needed ROHS3 compliant.","metaTitle":"STMicro BTA16-600CWRG Snubberless™ Triac, 16A 600V TO-220","metaDescription":"ST BTA16-600CWRG Alternistor triac, 16 A RMS, 600 V off-state, Snubberless™ for inductive loads.
