**onsemi** · MOSFETs · SOT-23

MGSF1N02LT1G from onsemi, in a SOT-23. 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 continuous gate-to-source voltage is rated ±20 Vdc. |
| 2 | Source | passive | Source terminal of the N-channel MOSFET; the source-drain body diode is rated for 0.6 A continuous current and 0.75 A pulsed current. |
| 3 | Drain | passive | Drain terminal of the N-channel MOSFET; the drain-to-source voltage is rated 20 Vdc and the continuous drain current is rated 750 mA at TA = 25°C. |
