DDTA144GCA-7

Overview

The DDTA144GCA-7 is a PNP pre-biased small signal transistor from Diodes Incorporated, housed in an SOT-23 surface mount package. It features epitaxial planar die construction and includes a built-in biasing resistor (R2) with a nominal value of 47kΩ. The device is qualified to AEC-Q101 standards for high reliability and complies with RoHS directives. Key electrical ratings include a collector-base voltage of -50V, collector-emitter voltage of -50V, and a maximum collector current of -100mA. The DC current gain (hFE) typically ranges from 68 under specified test conditions.

Feature Summary

Integrates a single internal biasing resistor (R2 only) to simplify circuit design
Constructed using epitaxial planar die technology for robust performance
Qualified to AEC-Q101 automotive standards ensuring high reliability
Manufactured as a lead, halogen, and antimony-free 'Green' device

Applications

Automotive electronic systems requiring AEC-Q101 compliant components
General-purpose switching applications utilizing pre-biased PNP transistors
Low-power digital logic interfacing circuits
Signal processing stages requiring integrated base biasing

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the date code aligns with manufacturing specifications if green molding compound compliance is critical for the project. Ensure the component meets all environmental regulations applicable to the target market before finalizing procurement orders.

Selection Notes

Select this component when a PNP transistor with an integrated 47kΩ base resistor is required. Consider the SOT-23 package constraints for board space. Evaluate the thermal resistance and power dissipation limits against the expected operating ambient temperature to ensure safe junction temperatures are maintained during operation.

Part Context

This part belongs to the DDTA R2-only series of pre-biased transistors. It serves as the PNP counterpart to the complementary NPN types available in the same family. The CA suffix indicates specific mechanical and material characteristics defined by the manufacturer for this product line.

Replacement Considerations

Direct substitutes within the same series include DDTA114GCA, DDTA124GCA, and DDTA115GCA, which share identical packaging and general electrical characteristics but differ in the nominal value of the internal biasing resistor.
