DDTA144ELP-7

Overview

The DDTA144ELP-7 is a PNP pre-biased small signal transistor manufactured by Diodes Incorporated, housed in an X1-DFN1006-3 leadless surface mount package. It features integrated base and emitter resistors with nominal values of 47 kΩ each (R1=R2). The device supports a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA, with a power dissipation rating of 250 mW at +25°C. It operates within a temperature range of -55°C to +150°C and meets AEC-Q101 standards for high reliability.

Feature Summary

• Ultra-small leadless surface mount package facilitates automated assembly processes.
• Totally lead-free and fully RoHS compliant with halogen and antimony-free green device specifications.

Applications

• Automotive electronic systems requiring high reliability components
• General-purpose switching applications in consumer electronics
• Interface circuits utilizing pre-biased transistor configurations

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging quantity and reel size. Confirm that the component meets all applicable environmental directives and quality standards required for the intended application before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing resistors is required. Ensure the design accommodates the 250 mW power dissipation limit and verify that the -50 V voltage rating aligns with the circuit's supply requirements.

Part Context

This part belongs to the DDTA144 series of pre-biased transistors from Diodes Incorporated. It utilizes the X1-DFN1006-3 package, which provides a minimal footprint suitable for space-constrained printed circuit board layouts while maintaining thermal performance through an exposed collector pad.

Replacement Considerations

DDTA144ELP-7B serves as an alternative packaging option within the same product family, offering identical electrical characteristics but differing in reel quantity.
