# KNH7650A

**KIA Semicon Tech** · MOSFETs · TO-3P

KNH7650A from KIA Semicon Tech, in a TO-3P. 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, with a gate-to-source voltage rating of ±30 V (VGSS) in the absolute maximum ratings. |
| 2 | Drain | passive | Drain terminal of the N-channel MOSFET, rated for a drain-to-source voltage of 500 V (VDSS) in the absolute maximum ratings. |
| 3 | Source | passive | Source terminal of the N-channel MOSFET, serving as the reference for the gate-to-source and drain-to-source ratings. |
