Overview
The AO4421 is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It features a drain-source voltage (VDS) rating of -60V. The device supports a continuous drain current (ID) of -6.2A at a gate-source voltage (VGS) of -10V. On-resistance characteristics include RDS(ON) values of less than 40mΩ at VGS=-10V and less than 50mΩ at VGS=-4.5V.
Feature Summary
- P-Channel enhancement mode field effect transistor construction
- Capable of handling -60V drain-source voltage ratings
- Supports -6.2A continuous drain current under specified gate drive conditions
Applications
- Power management circuits requiring P-channel switching
- Load switch applications in portable electronics
- DC-DC converter input protection stages
Procurement Notes
Verify the manufacturer designation on the component marking, as multiple vendors produce this part number. Confirm the specific datasheet version matches your design requirements for thermal and electrical parameters. Ensure the package type aligns with your PCB footprint specifications before ordering.
Selection Notes
Select this component when a -60V P-Channel MOSFET is required for low-side or high-side switching applications. Consider the RDS(ON) performance at -4.5V and -10V VGS to ensure compatibility with your logic level drivers. Evaluate thermal dissipation capabilities based on the expected continuous current load of -6.2A.
Part Context
This component belongs to the family of 60V P-Channel MOSFETs designed for general-purpose power switching. Similar devices from other manufacturers include the FQB27P06 and KSM17P06, which share comparable voltage and current ratings. These parts are commonly used in battery-powered systems and consumer electronics where efficient power control is necessary.
