CJU50SN10 from Changjing, in a TO-252-2L. 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 of the N-channel MOSFET, rated for a gate-source voltage VGS of ±20 V. |
| 2 | DRAIN | passive | Drain terminal of the MOSFET, rated for a drain-source voltage VDS of 100 V and a continuous drain current ID of 50 A. |
| 3 | SOURCE | passive | Source terminal of the MOSFET; the body diode has a forward voltage VSD of 1.3 V at IS = 20 A, VGS = 0 V. |
