# DMX0622E

**ARK micro** · MOSFETs · SOT-89

DMX0622E 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 is rated ±30 V, the cut-off voltage VGS(OFF) is -19 V to -25 V, and the gate-source ESD rating is 400 V (IEC, C=150pF, R=330Ω). |
| 2 | D | passive | Drain, also the SOT-89 tab; drain-to-source voltage is rated 70 V and continuous drain current 0.1 A (0.4 A pulsed). |
| 3 | S | passive | Source; the depletion-mode device is normally on with IDSS of at least 120 mA at VGS=0V, VDS=25V. |
