MOT · MOSFETs · TO-220
MOT20N50A from MOT, 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 | Gate | input | Gate terminal of the N-channel MOSFET; the gate-source voltage is rated at ±30 V (absolute maximum). |
| 2 | Drain | passive | Drain terminal of the N-channel MOSFET; drain-source voltage is rated at 500 V (BVDSS) and continuous drain current at 20 A (TC = 25°C). |
| 3 | Source | passive | Source terminal of the N-channel MOSFET and reference for the gate drive; body-diode continuous current is rated at 20 A. |
