PT8A2766ITAEX

Overview

The PT8A2766ITAEX is a power distribution switch and load driver manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.6 V to 5.5 V and supports an output current of 1 A. The device features a 1:1 input-to-output ratio and consumes an operating supply current of 20 uA. It is housed in a SOT-23-5 surface-mount package, designed for efficient power switching applications requiring low quiescent current and compact form factors.

Feature Summary

• Provides general-purpose power switching with a 1:1 input-to-output ratio
• Operates at low supply voltages starting from 1.6 V
• Delivers up to 1 A output current capability
• Features ultra-low operating supply current of 20 uA

Applications

• General purpose power distribution switching
• Load driver circuits for low-power devices
• Battery-powered systems requiring low standby current
• Portable electronics with space-constrained layouts

Procurement Notes

Verify the exact ordering suffix and package variant when sourcing, as Diodes Incorporated may offer related part numbers with slight parameter differences. Confirm RoHS compliance status through official documentation or authorized distributors. Ensure the supplier provides valid traceability data. Cross-reference the manufacturer part number against the latest datasheet revision to avoid discrepancies in electrical specifications or pin configurations during procurement.

Selection Notes

Select this component when a low-voltage, single-channel power switch is required with minimal quiescent current consumption. The 1.6 V minimum operating voltage makes it suitable for battery-backed systems. Consider the SOT-23-5 package size for PCB layout constraints. Verify that the 1 A output current meets the load requirements without exceeding thermal limits in the intended application environment.

Part Context

This component belongs to the power management IC category, specifically under power distribution switches and load drivers. It is part of Diodes Incorporated's portfolio of PMIC solutions designed for portable and battery-operated devices. The active lifecycle status indicates ongoing production support. Related products in this family include other single-channel switches with varying current ratings or voltage thresholds.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Diodes Incorporated's official cross-reference tools or authorized distributor databases for compatible alternatives. Ensure any replacement matches the SOT-23-5 package, 1.6–5.5 V operating range, and 1 A current rating.
