AO4914

Overview

The AO4914 is a dual N-channel MOSFET array manufactured by Alpha & Omega Semiconductor Inc. It features a logic-level gate threshold designed for low-voltage drive applications. The device integrates two independent N-channel enhancement mode field-effect transistors within a single package to optimize board space and simplify circuit design. Key electrical parameters include a drain-source voltage (Vdss) of 30V and a continuous drain current (Id) rated at 11A at 25°C ambient temperature. The maximum on-resistance (Rds(on)) is specified as 12.5mΩ at Vgs=10V and Id=11A, ensuring efficient power handling with minimal conduction losses.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure that the component source is an authorized distributor to guarantee authenticity and traceability. Check for RoHS compliance status if environmental regulations apply to the end product assembly process.

Selection Notes

Select this component when a dual N-channel configuration is required for space-constrained designs. Evaluate the 30V voltage rating and 11A current capacity against the system's peak load requirements. Consider the thermal performance characteristics relative to the available PCB copper area for heat dissipation during continuous operation.
