FDS8958B from TECH PUBLIC, in a SOIC-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 | S1 | passive | Source of MOSFET 1 in the dual N/P-channel pair, with gate-source voltage limited to ±20V. |
| 2 | G1 | input | Gate of MOSFET 1, with an absolute maximum gate-source voltage of ±20V. |
| 3 | S2 | passive | Source of MOSFET 2 in the dual N/P-channel pair, with gate-source voltage limited to ±20V. |
| 4 | G2 | input | Gate of MOSFET 2, with an absolute maximum gate-source voltage of ±20V. |
| 5 | D2 | passive | Drain of MOSFET 2, tied to pin 6; the datasheet rates drain-source voltage at 30V (N-CH) or -30V (P-CH). |
| 6 | D2 | passive | Drain of MOSFET 2, tied to pin 5; the datasheet rates drain-source voltage at 30V (N-CH) or -30V (P-CH). |
| 7 | D1 | passive | Drain of MOSFET 1, tied to pin 8; the datasheet rates drain-source voltage at 30V (N-CH) or -30V (P-CH). |
| 8 | D1 | passive | Drain of MOSFET 1, tied to pin 7; the datasheet rates drain-source voltage at 30V (N-CH) or -30V (P-CH). |
