AO4459

Alpha Omega Semicon · MOSFETs · SOIC-8

AO4459 from Alpha Omega Semicon, in a SOIC-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, referenced to the gate-source limit of ±20 V and the drain-source voltage of -30 V.
2 S passive Source terminal of the P-channel MOSFET, referenced to the gate-source limit of ±20 V and the drain-source voltage of -30 V.
3 S passive Source terminal of the P-channel MOSFET, referenced to the gate-source limit of ±20 V and the drain-source voltage of -30 V.
4 G input Gate of the MOSFET; gate-source voltage is rated at ±20 V.
5 D passive Drain terminal; drain-source voltage is rated at -30 V and continuous drain current at -6.5 A (TA=25°C).
6 D passive Drain terminal; drain-source voltage is rated at -30 V and continuous drain current at -6.5 A (TA=25°C).
7 D passive Drain terminal; drain-source voltage is rated at -30 V and continuous drain current at -6.5 A (TA=25°C).
8 D passive Drain terminal; drain-source voltage is rated at -30 V and continuous drain current at -6.5 A (TA=25°C).
