**STMicroelectronics** · MOSFETs · TO-220

STP9N65M2 from STMicroelectronics, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate. Insulated MOS control terminal; VGS(th) = 2-4 V, |VGS| max ±25 V. Zener-protected. Intrinsic gate resistance ~6.6 Ω; total gate charge Qg ≈ 10.3 nC at VGS = 0→10 V. |
| 2 | D | passive | Drain. Also electrically bonded to the metal TAB of the TO-220 package. Drain-source breakdown V(BR)DSS = 650 V min; continuous ID = 5 A at TC = 25 °C, pulsed IDM = 20 A; RDS(on) ≤ 0.90 Ω at VGS = 10 V, ID = 2.5 A. |
| 3 | S | passive | Source. Reference terminal for VGS and the anode of the intrinsic body diode (VSD ≈ 1.6 V at ISD = 5 A, VGS = 0). Body-diode reverse-recovery trr ≈ 276 ns at 25 °C. |
| TAB | D | passive | Metal mounting TAB, internally shorted to the Drain (pin 2). Provides the primary thermal path (Rthj-case = 2.08 °C/W for TO-220). Insulation withstand voltage 2.5 kV RMS from leads to external heat sink. |
