SSM3J334R from TOSHIBA, in a SOT-23F. 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 gate-source voltage VGSS is limited to ±20 V (absolute maximum), and the gate threshold Vth is -0.8 V to -2.0 V at VDS = -10 V, ID = -100 µA. |
| 2 | Source | passive | Source terminal; the drain-source breakdown voltage V(BR)DSS is -30 V minimum at ID = -10 mA, VGS = 0 V, and the drain-source forward voltage VDSF is 1.2 V maximum at ID = 4.0 A, VGS = 0 V. |
| 3 | Drain | passive | Drain terminal; the drain-source voltage VDSS is -30 V and the DC drain current ID is -4 A (pulse IDP -16 A, PW ≤ 1 ms, duty ≤ 1%) as absolute maximum ratings. |
