CJQ4459A

Changjing · MOSFETs · SOP-8

CJQ4459A from Changjing, in a SOP-8. 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 P-channel MOSFET; the device is rated for a drain-source voltage of -30 V and continuous drain current of -6 A.
2 S passive Source terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -30 V and continuous drain current of -6 A.
3 S passive Source terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -30 V and continuous drain current of -6 A.
4 G input Gate terminal of the MOSFET; the gate-source voltage must stay within ±20 V.
5 D passive Drain terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -30 V and continuous drain current of -6 A.
6 D passive Drain terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -30 V and continuous drain current of -6 A.
7 D passive Drain terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -30 V and continuous drain current of -6 A.
8 D passive Drain terminal of the P-channel MOSFET; the device is rated for a drain-source voltage of -30 V and continuous drain current of -6 A.
