# DTU09N03-JSM

**JSMSEMI** · MOSFETs · TO-252

DTU09N03-JSM from JSMSEMI, 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 | G | input | Gate of the N-channel MOSFET, with a maximum gate-source voltage of ±20 V and a threshold of 1 V min to 2.5 V max. |
| 2 | D | passive | Drain of the N-channel MOSFET, rated for 30 V drain-source and 80 A continuous at Tc=25°C; the package tab is also drawn as the drain. |
| 3 | S | passive | Source of the N-channel MOSFET, with a continuous source (body diode) current rating of 80 A. |
