**Texas Instruments** · MOSFETs · TO-220

CSD18510KCS from Texas Instruments, 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 MOSFET; gate-to-source voltage is rated ±20 V in the absolute maximum ratings. |
| 2 | Drain | passive | Drain terminal of the MOSFET; drain-to-source voltage is rated 40 V with continuous drain current of 200 A (package limited). |
| 3 | Source | passive | Source terminal of the MOSFET, the reference for the ±20 V gate-to-source rating in the absolute maximum ratings. |
