Overview
The AO3421L is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver excellent RDS(ON) and low gate charge, making it suitable for load switch and PWM applications. The device operates with a drain-source voltage of -30V and a continuous drain current of -2.6A at VGS = -10V. Key electrical parameters include an on-resistance of less than 130mΩ at VGS = -10V and less than 200mΩ at VGS = -4.5V. The component is RoHS compliant and the AO3421L variant is halogen-free.
Feature Summary
- Advanced trench technology provides excellent on-resistance and low gate charge characteristics.
- Designed for efficient operation as a load switch or in pulse-width modulation (PWM) applications.
- Electrically identical to the standard AO3421 model while offering halogen-free compliance.
Applications
- Load switching circuits
- Pulse-width modulation (PWM) control systems
Procurement Notes
Verify that the specific order corresponds to the AO3421L designation to ensure halogen-free material compliance. Confirm the package type matches the required TO-236 (SOT-23) footprint. Ensure the application environment remains within the specified consumer market scope, as critical life support uses are not authorized by the manufacturer.
Selection Notes
Select this component when a P-channel MOSFET with a -30V rating and approximately -2.6A continuous current capability is required. Consider the low gate charge values for high-frequency switching efficiency. Verify that the thermal management design accommodates the junction-to-ambient resistance ratings provided in the datasheet for the intended operating conditions.
Part Context
This part belongs to the Alpha & Omega Semiconductor AO34xx series of small-signal MOSFETs. These devices are widely used in portable electronics and battery-powered equipment due to their compact SOT-23 packaging and efficient power handling capabilities relative to their size.
Replacement Considerations
The AO3421L is electrically identical to the AO3421. Substitution should be limited to parts explicitly documented as equivalent by the manufacturer or verified through comprehensive parameter matching.
