T3050H-6I

STMicroelectronics · TRIACs · TO-220AB

T3050H-6I from STMicroelectronics, in a TO-220AB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Main terminal A1 (reference terminal of the triac); the datasheet states its electrical characteristics for both polarities of A2 referenced to A1.
2 A2 passive Main terminal A2 of the triac, rated for 30 A RMS on-state current (IT(RMS)) and 600 V VDRM/VRRM.
3 G input Gate trigger input with IGT of 50 mA max at VD = 12 V, RL = 33 Ω (T3050H), VGT max 1.0 V, and peak gate current IGM of 4 A (tp = 20 µs).
