T1635H-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 1 (MT1); on-state RMS current 16 A at Tc = 113 °C for TO-220AB Ins.; reference terminal for dV/dt, (dI/dt)c and gate trigger specs. |
| 2 | A2 | passive | Main terminal 2 (MT2); internally connected to the isolated ceramic-pad tab (2500 VRMS insulation rating); blocking voltage VDRM/VRRM = 600 V; surge peak ITSM = 160 A (50 Hz, 20 ms). |
| 3 | G | input | Gate trigger input; IGT max 35 mA (T1635H) in quadrants I-II-III at VD = 12 V, RL = 33 Ω; VGT max 1.0 V; peak gate current IGM 4 A (tp = 20 µs, Tj = 150 °C); average gate power dissipation PG(AV) 1 W. |
