AP2331W-7-01

Overview

The AP2331W-7-01 is a single-channel, current-limited high-side load switch from Diodes Incorporated. It operates within an input voltage range of 2.7 V to 5.2 V and supports a continuous output current of 0.2 A. The device features a low on-resistance (RdsOn) of 350 mΩ and is housed in a compact SC-59 package with three pins. It functions as a power distribution switch optimized for hot-swap applications in 5V-powered systems.

Feature Summary

• Provides current-limited protection for downstream loads
• Optimized for hot-swap operations in 5V systems
• High-side switching configuration

Applications

• Hot-swap applications in 5V-powered systems
• Power distribution switches
• USB power switch circuits

Procurement Notes

Verify the specific suffix (-01) against official Diodes Incorporated documentation to confirm exact ordering and revision details. Ensure compatibility with system voltage ranges (2.7 V to 5.2 V) and thermal requirements (-40°C to 85°C). Confirm package type SC-59 matches PCB footprint specifications before procurement.

Selection Notes

Select this component for applications requiring precise current limiting and hot-swap capability in low-voltage environments. The 350 mΩ on-resistance minimizes power loss, while the SC-59 package suits space-constrained designs. Ensure the load current does not exceed the 0.2 A rating for reliable operation.
