BTA12-600TWRG

STMicroelectronics · Thyristors (SCR)/Modules · TO-220

BTA12-600TWRG from STMicroelectronics, in a TO-220. 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, the reference terminal for the A2 voltage and the gate trigger, carrying up to 12 A RMS on-state current (TO-220AB Ins. at Tc = 90 °C).
2 A2 passive Main terminal A2, blocking VDRM/VRRM of 600 V for the BTA12-600TW and carrying 12 A RMS on-state current at Tc = 90 °C; the insulated tab (rated 2500 VRMS) is not an electrical connection.
3 G input Gate trigger input, with IGT max 5 mA (VD = 12 V, RL = 30 Ω, quadrants I-II-III), VGT max 1.3 V and peak gate current IGM of 4 A (tp = 20 µs).
