DMZ1521E from ARK micro, in a SOT-23. 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; depletion-mode device (normally on) with gate-to-source cut-off voltage -7 V to -5 V and absolute maximum VGS of ±20 V. |
| 2 | S | passive | Source terminal of the depletion-mode MOSFET, with continuous drain current rated 0.2 A and pulsed 0.6 A. |
| 3 | D | passive | Drain terminal (the single lead on one side of the package) rated for 150 V drain-to-source (VDSX) and 150 V drain-to-gate (VDGX). |
