**Cmos(广东场效应半导体)** · IC · TO-220

CMP90N68K from Cmos(广东场效应半导体), 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 | G | input | Gate terminal; the gate-source voltage is rated at ±25 V (VGS) in the absolute maximum ratings. |
| 2 | D | passive | Drain terminal; the datasheet rates the drain-source voltage at 68 V and the continuous drain current at 90 A at TC=25℃. |
| 3 | S | passive | Source terminal; the datasheet gives no pin-specific electrical limit for this pin. |
