KNC2404A from KIA Semicon Tech, in a TO-263-6L. 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; gate-to-source voltage is limited to ±25 V (VGSS) and the gate threshold is 2 V min to 4 V max at 250 µA. |
| 2 | Source | passive | Source terminal, connected to the other source pins; continuous drain current is 190 A silicon limited and 120 A package limited at TC=25°C. |
| 3 | Source | passive | Source terminal, connected to the other source pins; body diode continuous forward current is 190 A. |
| 4 | Drain | passive | Drain, brought out as the exposed tab (pin 4 is the tab in the package drawing, with the middle lead absent); drain-to-source voltage is 40 V max (VDSS). |
| 5 | Source | passive | Source terminal, connected to the other source pins; pulsed drain current is 480 A at TC=25°C. |
| 6 | Source | passive | Source terminal, connected to the other source pins; RDS(on) is 2.2 mΩ typ and 3.5 mΩ max at VGS=10 V, IDS=30 A. |
| 7 | Source | passive | Source terminal, connected to the other source pins; junction and storage temperature range is -55 to 150 °C. |
