DMN601WKQ from Leiditech, in a SOT-323-3. 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 of the N-channel MOSFET, limited to ±20 Vdc continuous and ±40 Vdc non-repetitive (tp≤50µs), with a gate threshold voltage of 1.0 to 2.5 Vdc at ID = 250 µAdc. |
| 2 | Source | passive | Source terminal of the MOSFET, which carries up to 115 mAdc continuous source (body diode) current and 800 mAdc pulsed. |
| 3 | Drain | passive | Drain terminal of the MOSFET, rated for 60 Vdc drain-source voltage and ±115 mAdc continuous drain current at TC = 25°C (±800 mAdc pulsed). |
