Overview
The AO4202 is a 30V N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to achieve low on-resistance and gate charge, supporting operation with gate voltages as low as 2.5V. The device is housed in a TO-236 (SOT-23) package and is suitable for load switch and PWM applications.
Feature Summary
- Advanced trench technology for excellent RDS(ON) and low gate charge
- Logic-level gate drive capability operating down to 1.8V
- Suitable for use as a load switch or in PWM applications
Applications
- Load switching circuits
- Pulse Width Modulation (PWM) control
- Low voltage power management systems
Procurement Notes
Verify the specific ordering suffix when purchasing. The standard AO4202 is lead-free and meets ROHS specifications. The AO4202L variant is designated as a Green Product but shares identical electrical characteristics with the standard version. Confirm package type and compliance status with the supplier before finalizing orders.
Selection Notes
Select this component for designs requiring efficient switching at low gate drive voltages. The SOT-23 package offers space-saving benefits for portable electronics. Ensure the application voltage remains within the 30V drain-source limit and that thermal constraints are managed given the small form factor.
Part Context
This part belongs to Alpha & Omega Semiconductor’s portfolio of N-Channel MOSFETs designed for general-purpose power switching. It complements other devices in the series by providing a balance of performance and cost-effectiveness for consumer and industrial electronic applications requiring compact surface-mount solutions.
Replacement Considerations
Check for electrically identical alternatives such as the AO4202L, which offers green product packaging options without changing functionality. Verify pinout compatibility and thermal resistance ratings when considering cross-brand substitutes.
