AOC2403

Overview

The AOC2403 is a 20V P-Channel MOSFET utilizing advanced trench technology. It features a drain-source voltage (BVDSS) of -20V and a continuous source current (ID) of -1.8A at VGS=-4.5V. The on-resistance (RDS(ON)) is less than 95mΩ at VGS=-4.5V, rising to less than 200mΩ at VGS=-1.5V. Key dynamic parameters include a total gate charge (Qg) of 4.8nC and a forward transconductance (gFS) of 7S. The device operates within a junction temperature range of -55°C to 150°C.

Feature Summary

Advanced trench technology provides excellent on-resistance and low gate charge.
Capable of operation with gate voltages as low as 1.5V.
Retains an 8V maximum gate-source voltage rating.

Applications

Procurement Notes

Verify the specific package type AlphaDFN 0.97x0.97_4 against your PCB footprint requirements. Confirm that the component's qualification for the consumer market aligns with your project's intended use case. Ensure that any application does not involve life support devices or systems, as such uses are explicitly unauthorized by the manufacturer.

Selection Notes

Select this component for low-voltage switching applications requiring efficient performance at reduced gate drive voltages. The low gate charge supports high-frequency operation, while the specified on-resistance values indicate suitability for moderate current loads up to 1.8A. Evaluate thermal management needs based on the provided transient thermal impedance data.

Part Context

This part belongs to the P-Channel MOSFET category from Alpha & Omega Semiconductor Inc. It is designed using trench technology to optimize conduction losses and switching speeds. The device is marketed primarily for consumer electronics applications, offering a compact solution for power management tasks in portable and space-constrained devices.
