IRF640NPBF from Infineon Technologies, in a TO-220AB. 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 terminal; high-impedance control input with V_GS(th) = 4.0 V (typ.) and total gate charge Q_g = 11 nC (typ.) at V_GS = 10 V. |
| 2 | D | passive | Drain terminal; also connected to the mounting tab; rated V_DSS = 200 V and continuous drain current I_D = 18 A at T_C = 25 °C with R_DS(on) = 0.15 Ω (typ.) at V_GS = 10 V. |
| 3 | S | passive | Source terminal of N-channel HEXFET power MOSFET; body diode forward voltage V_SD = 1.3 V (typ.) at I_S = 11 A. |
