STY145N65M5 from STMicroelectronics, in a TO-247-3. 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 | G | input | Gate control input; VGS abs. max ±25 V, gate threshold VGS(th) = 3-5 V (VDS = VGS, ID = 250 µA), total gate charge Qg = 414 nC typ. at VDD = 520 V / ID = 69 A / VGS = 10 V. |
| 2 | D | passive | Drain; also internally connected to the back-metal heat-sink tab. V(BR)DSS ≥ 650 V, ID = 138 A continuous (TC = 25 °C) / 87 A (TC = 100 °C), IDM = 552 A pulsed, RDS(on) = 0.015 Ω max (VGS = 10 V, ID = 69 A). |
| 3 | S | passive | Source; body-diode forward voltage VSD = 1.5 V typ. at ISD = 138 A (pulsed), reverse recovery time trr = 568 ns typ. at ISD = 138 A, di/dt = 100 A/µs, VDD = 100 V. |
