# KPD7910A

**KIA Semicon Tech** · MOSFETs · TO-252

KPD7910A from KIA Semicon Tech, in a TO-252. 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 | MOSFET gate terminal; the datasheet rates the gate-source voltage VGS at ±20 V. |
| 2 | Drain | passive | MOSFET drain terminal; the datasheet rates the drain-to-source voltage VDSS at -100 V and the continuous drain current ID at -28 A (TC = 25 ºC). |
| 3 | Source | passive | MOSFET source terminal; the datasheet gives no separate rating for this pin beyond the device-level VDSS and VGS limits. |
