UMW · MOSFETs · TO-220
IRFZ44N from UMW, 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 | G | input | Gate terminal of the N-channel MOSFET; the datasheet limits gate-source voltage to VGS = ±20 V (absolute maximum). |
| 2 | D | passive | Drain terminal; the datasheet rates VDS at 60 V and continuous drain current ID at 50 A (TC = 25°C). |
| 3 | S | passive | Source terminal, the reference for VGS and the return path for drain current; the datasheet gives no separate pin limit for it. |
