AO4614BL_103

Overview

The AO4614BL_103 is a dual complementary MOSFET from Alpha & Omega Semiconductor, integrating an N-channel and P-channel device in a single SOIC-8 package. The N-channel unit supports a drain-source voltage of 40V with a continuous drain current of 6A at VGS=10V, while the P-channel unit handles -40V and -5A at VGS=-10V. Both channels feature low on-resistance, specified as less than 30mΩ for the N-channel and 45mΩ for the P-channel at VGS=±10V. The component operates within a junction temperature range of -55°C to 150°C and includes thermal characteristics such as a steady-state junction-to-ambient resistance of 74°C/W.

Feature Summary

• Integrates complementary N-channel and P-channel MOSFETs into a single surface-mount package.
• Utilizes advanced trench technology to achieve low gate charge and excellent on-resistance.
• Includes 100% UIS (Unclamped Inductive Switching) testing for both channel types.

Applications

• H-bridge circuits
• Inverters

Procurement Notes

Verify that the ordering suffix '_103' corresponds to the specific tape and reel packaging configuration defined by Alpha & Omega Semiconductor. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation, as standard variants may differ in environmental certification details.

Selection Notes

Select this component when a compact solution for low-voltage switching is required. The complementary nature simplifies driver design for half-bridge or full-bridge topologies. Ensure the application stays within the 40V rating and consider the thermal resistance values for adequate heat dissipation on the PCB.

Part Context

This part belongs to the AO4614B series of dual MOSFETs manufactured by Alpha & Omega Semiconductor. It is designed as a space-saving alternative to discrete components, offering matched electrical characteristics for balanced performance in push-pull configurations.

Replacement Considerations

Direct pin-compatible replacements include other dual N+P MOSFETs in SOIC-8 packages with similar 40V ratings and comparable on-resistance values. Verify gate threshold voltages and thermal resistance specifications before substitution.
