**ARK micro** · MOSFETs · SOT-89

DMX0615E from ARK micro, 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 | G | input | Gate; Gate-to-Source voltage max ±30 V, cut-off VGS(OFF) -13 V to -20 V, and gate ESD rating 400 V (IEC, C=150pF, R=330Ω). |
| 2 | D | passive | Drain (also the SOT-89 tab); Drain-to-Source voltage max 70 V, continuous drain current 0.1 A, pulsed 0.4 A. |
| 3 | S | passive | Source; depletion-mode MOSFET source terminal, with output voltage clamped to about VGS(OFF) below the input. |
