# STP110N10F7

**STMicroelectronics** · MOSFETs · TO-220

STP110N10F7 from STMicroelectronics, 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 control input terminal; accepts gate-source voltage (VGS) to control the N-channel MOSFET switching state. |
| 2 | Drain | output | Drain terminal; primary current path for the N-channel MOSFET, also connects to metal tab for thermal management and case dissipation. |
| 3 | Source | power_in | Source terminal; serves as reference for gate-source voltage and return path for drain current with up to 110 A maximum continuous rating. |
