# OSPF5N20

**OSEN** · MOSFETs · TO-220F

OSPF5N20 from OSEN, in a TO-220F. 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 controlling the channel, with a maximum gate-source voltage of ±20 V and a threshold of 2.0 to 4.0 V at VDS=VGS, ID=250µA. |
| 2 | Drain | passive | Drain terminal rated for 200 V drain-source voltage, 5 A continuous drain current and 20 A pulsed drain current. |
| 3 | Source | passive | Source terminal of the N-channel MOSFET, which is the reference for gate drive and the anode side of the body diode rated for 5 A continuous forward current. |
