DDA144EK-7-F

Overview

The DDA144EK-7-F is a dual PNP digital transistor manufactured by Diodes Incorporated, housed in an SOT-26-6 surface-mount package. It features two integrated PNP transistors with typical input resistors of 47 kOhms and a resistor ratio of 1. The device supports a continuous collector current of 100 mA and a minimum DC current gain (hfe) of 68. It operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 300 mW.

Feature Summary

• Dual configuration integrating two PNP transistors for space-efficient circuit design
• Integrated base resistors simplify biasing networks and reduce component count
• High thermal stability supporting operation up to 150°C

Applications

• General-purpose switching applications requiring dual PNP logic control
• Interface circuits between microcontrollers and peripheral devices
• Level shifting and buffer stages in digital logic systems

Procurement Notes

Verify availability status as the component is listed as End-of-Life or obsolete in some distributor records. Confirm final procurement details directly with Diodes Incorporated or authorized partners, as standard distribution channels may not stock this specific part number. Ensure compliance with RoHS requirements before integration.

Selection Notes

Select this component when a dual PNP digital transistor with 47 kOhm base resistors is required in an SOT-26-6 package. Compare against single-transistor alternatives if only one channel is needed, or consider other packages like SOT-563 if pinout compatibility differs. Verify that the 100 mA current rating meets the load requirements of the target application.

Part Context

This part belongs to the DDA144 series of digital transistors from Diodes Incorporated. It shares electrical characteristics with other variants in the series but differs in packaging and configuration. The DDA prefix indicates a dual PNP structure, distinguishing it from NPN or single-transistor counterparts like the DDTA or DDTC series.

Replacement Considerations
