Overview
The AO4614B is a dual complementary MOSFET from Alpha & Omega Semiconductor, integrating an N-channel and a P-channel device in a single SOIC-8 package. The N-channel unit features a drain-source voltage of 40V and a continuous drain current of 6A at 25°C, with a maximum on-resistance of 30mΩ at VGS=10V. The P-channel unit offers a -40V breakdown voltage and a -5A continuous current rating, exhibiting a maximum on-resistance of 45mΩ at VGS=-10V. Both channels are rated for a junction temperature range of -55°C to 150°C and utilize advanced trench technology.
Feature Summary
- Complementary N-channel and P-channel MOSFETs integrated into a single surface-mount package
- Advanced trench technology designed to provide low gate charge and excellent on-resistance
- Validated for 100% unclamped inductive switching (UIS) testing
Applications
- H-bridge circuits
- Inverters
- Motor control applications
Procurement Notes
Verify the component against official manufacturer datasheets to confirm pinout compatibility and electrical ratings before integration. Ensure that the specific lot and revision match the design requirements. Confirm compliance with RoHS standards and lead-free specifications as documented by the supplier. Validate thermal management strategies based on the provided junction-to-ambient resistance values.
Selection Notes
Select this component when a compact solution for complementary switching is required. The SOIC-8 package minimizes board space compared to discrete components. Consider the thermal characteristics and on-resistance values at the intended operating gate voltages. Verify that the continuous and pulsed current ratings align with the load requirements.
Part Context
This part belongs to the AO46xx series of dual MOSFETs manufactured by Alpha & Omega Semiconductor. It is designed for consumer electronics and general-purpose switching applications. The product is qualified for the consumer market and is not authorized for use in life support devices or critical systems without explicit authorization.
Replacement Considerations
Direct replacements must maintain the SOIC-8 footprint and complementary N/P channel configuration. Verify that substitute parts meet or exceed the 40V/6A and -40V/-5A ratings. Check for equivalent on-resistance and gate charge specifications to ensure similar switching performance.
