**JSMSEMI** · MOSFETs · SOP-8

FDS4435BZ-JSM from JSMSEMI, in a SOP-8. 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 | S | passive | Source of the P-channel MOSFET; pin 1 is marked by the dot on the package top view. |
| 2 | S | passive | Source of the P-channel MOSFET, connected in parallel with the other source pins. |
| 3 | S | passive | Source of the P-channel MOSFET, connected in parallel with the other source pins. |
| 4 | G | input | Gate of the P-channel MOSFET; the Gate-Source voltage is rated at ±20 V. |
| 5 | D | passive | Drain of the P-channel MOSFET, rated at -30 V drain-source voltage and -9.7 A continuous drain current at VGS=10 V. |
| 6 | D | passive | Drain of the P-channel MOSFET, connected in parallel with the other drain pins. |
| 7 | D | passive | Drain of the P-channel MOSFET, connected in parallel with the other drain pins. |
| 8 | D | passive | Drain of the P-channel MOSFET, connected in parallel with the other drain pins. |
