Overview
The AO4443L is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to achieve excellent RDS(ON) and ultra-low gate charge characteristics. The device is rated for a Drain-Source Voltage (VDS) of -40V and a continuous Drain Current (ID) of -6.5A. At VGS = -10V, the maximum on-resistance is less than 42mΩ, while at VGS = -4.5V, it is less than 63mΩ. Standard packaging is available in lead-free configurations compliant with RoHS and Sony 259 specifications.
Feature Summary
- Advanced trench technology provides low on-resistance and reduced switching losses.
- Optimized for load switch applications and Pulse Width Modulation (PWM) operations.
- Ultra-low gate charge minimizes drive power requirements.
Applications
- Load switching circuits
- Pulse Width Modulation (PWM) control
- Low-side power management
Procurement Notes
Verify that the specific order suffix corresponds to the 'Green Product' variant if environmental compliance beyond standard RoHS is required. Confirm package integrity upon receipt as components are supplied in tape and reel formats. Ensure storage conditions align with manufacturer guidelines to maintain solderability and electrical performance before assembly.
Selection Notes
Select this component when a P-channel MOSFET with a 40V voltage rating and approximately 6.5A current capacity is needed. The low gate charge makes it suitable for high-frequency PWM applications where drive efficiency is critical. Verify that the logic level requirements match the system's VGS capabilities, noting the distinct resistance values at -10V and -4.5V gate voltages.
Part Context
The AO4443L belongs to the AO4443 product family from Alpha & Omega Semiconductor. It shares identical electrical characteristics with the standard AO4443 but represents the Green Product ordering option. This variant adheres to specific environmental standards, ensuring compliance with restricted substance regulations while maintaining the performance profile of the base trench technology device.
Replacement Considerations
The AO4443L is electrically identical to the AO4443. Designers may substitute one for the other without modifying circuit parameters, provided the specific environmental or ordering suffix requirements are met.
