CJU100N03

Changjing · MOSFETs · TO-252-2L

CJU100N03 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; gate-source voltage is rated at ±20V (IGSS tested at VGS=±20V) with a threshold of 1.0V min to 3.0V max at ID=250µA.
2 DRAIN passive Drain terminal, also the exposed tab; drain-source breakdown is 30V min at ID=250µA and RDS(on) is 6.5mΩ typ at VGS=10V.
3 SOURCE passive Source terminal; continuous source-drain diode current is 100A with a 400A pulsed rating.
