KNY3403B from KIA Semicon Tech, 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 | Source | passive | Source terminal of the N-channel MOSFET, sharing the body diode path with the drain-source ratings of 30 V VDSS and 85 A continuous drain current. |
| 2 | Source | passive | Source terminal of the N-channel MOSFET, sharing the body diode path with the drain-source ratings of 30 V VDSS and 85 A continuous drain current. |
| 3 | Source | passive | Source terminal of the N-channel MOSFET, sharing the body diode path with the drain-source ratings of 30 V VDSS and 85 A continuous drain current. |
| 4 | Gate | input | Gate terminal of the MOSFET; gate-source voltage is limited to ±20 V (VGSS). |
| 5 | Drain | passive | Drain terminal of the MOSFET; drain-source voltage is rated 30 V (VDSS) with 85 A continuous drain current at TC = 25 ºC. |
| 6 | Drain | passive | Drain terminal of the MOSFET; drain-source voltage is rated 30 V (VDSS) with 85 A continuous drain current at TC = 25 ºC. |
| 7 | Drain | passive | Drain terminal of the MOSFET; drain-source voltage is rated 30 V (VDSS) with 85 A continuous drain current at TC = 25 ºC. |
| 8 | Drain | passive | Drain terminal of the MOSFET; drain-source voltage is rated 30 V (VDSS) with 85 A continuous drain current at TC = 25 ºC. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
