AP2281-3WG-7

Overview

The AP2281-3WG-7 is a single-channel load switch from Diodes Incorporated, designed for power distribution applications. It operates within a supply voltage range of 1.5 V to 6 V and supports an output current of 2 A. The device features a maximum on-resistance of 280 mOhms and exhibits typical rise and fall times of 1 µs. It is housed in a compact SOT-26-6 surface-mount package and functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Single-channel load switch configuration for efficient power distribution
• Capable of handling up to 2 A output current with low on-resistance
• Integrated enable input for precise control of power sequencing
• Designed for surface-mount assembly in space-constrained environments

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing low quiescent current operation
• General-purpose load switching in consumer electronics
• Peripheral power distribution in mobile computing hardware

Procurement Notes

Verify the specific suffix WG-7 against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint for the SOT-26-6 package. Confirm that the 1.5 V to 6 V operating range aligns with your system's voltage rails. Check for any recent product change notifications regarding manufacturing sites or materials.

Selection Notes

Select this component when a single-channel switch with 2 A capacity is required within a 6 V limit. The 280 mOhm on-resistance suits applications where moderate conduction loss is acceptable. Consider the SOT-26-6 package if board space allows for slightly larger footprints compared to SOT-23 variants. Verify that the 1 µs switching speed meets your system's timing requirements for power sequencing.
