**CRMICRO** · MOSFETs · TO-263

CRSS042N10N from CRMICRO, in a TO-263. 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; gate-source voltage limit is ±20 V and the gate threshold VGS(th) is 2 to 4 V (3 V typ.) at ID=250 µA. |
| 2 | D | passive | Drain, also connected to the exposed mounting tab; VDS max is 100 V and continuous ID is 120 A (package limit, TC=25°C). |
| 3 | S | passive | Source; connects to the body diode anode, and the pulsed drain current limit is 480 A. |
