DN1509N8-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 terminal; the datasheet limits gate-to-source voltage to ±20V and gives a gate-to-source off voltage of -1.8V to -3.5V at ID = 10µA. |
| 2 | DRAIN | passive | Drain terminal; drain-to-source breakdown voltage (BVDSX) is 90V minimum, and continuous drain current is limited to 360 mA for the SOT-89 package. |
| 3 | SOURCE | passive | Source terminal; saturated drain-to-source current (IDSS) is 300 mA minimum at VGS = 0V and VDS = 25V. |
