**Microchip Tech** · MOSFETs · SOT-89

DN2540N8-G from Microchip Tech, in a SOT-89. 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 control input with a gate-to-source rating of ±20V and a gate-to-source off voltage of -1.5V to -3.5V (depletion mode, normally on). |
| 2 | DRAIN | passive | Drain terminal, also connected to the SOT-89 tab, with a minimum drain-to-source breakdown of 400V and a continuous drain current of 170mA in TO-243AA. |
| 3 | SOURCE | passive | Source terminal, the reference for the gate voltage, carrying up to 170mA continuous drain current in TO-243AA. |
