JSMSEMI · MOSFETs · SOT-23-3
FDV301N-JSM from JSMSEMI, in a SOT-23-3. 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; the datasheet gives no pin-specific voltage limit for it. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, shown as the source node in the equivalent circuit; the datasheet gives no pin-specific limit for it. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; the datasheet gives no pin-specific current or voltage limit for it. |
