**TECH PUBLIC** · MOSFETs · DFN-8(5x6)

BSC057N08NS3G-TP from TECH PUBLIC, in a DFN-8(5x6). 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 terminal of the N-channel MOSFET; the datasheet marking diagram labels pin 1 as S. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; the datasheet marking diagram labels pin 2 as S. |
| 3 | S | passive | Source terminal of the N-channel MOSFET; the datasheet marking diagram labels pin 3 as S. |
| 4 | G | input | Gate terminal; gate-source voltage is rated ±20 V absolute maximum, with a threshold VGS(th) of 2 V min, 3 V typ and 4 V max. |
| 5 | D | passive | Drain terminal; drain-source voltage is rated 85 V absolute maximum. |
| 6 | D | passive | Drain terminal; drain-source voltage is rated 85 V absolute maximum. |
| 7 | D | passive | Drain terminal; drain-source voltage is rated 85 V absolute maximum. |
| 8 | D | passive | Drain terminal; drain-source voltage is rated 85 V absolute maximum. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
