DDTA124TCA-7

Overview

The DDTA124TCA-7 is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT23 package. It integrates a single built-in biasing resistor (R1) with a nominal value of 22 kΩ. The device features epitaxial planar die construction and operates within a collector-emitter voltage range of -50 V and a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, with a thermal resistance from junction to ambient air of 625 °C/W. The DC current transfer ratio (hFE) ranges from 100 to 600 under standard test conditions.

Feature Summary

Integrates a single built-in biasing resistor for simplified circuit design
Utilizes epitaxial planar die construction for reliable performance
Complies with RoHS standards and is halogen and antimony free

Applications

Switching applications requiring integrated base biasing
General-purpose digital logic interfacing
Low-power signal processing circuits

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details and availability status. Confirm that the component meets all required environmental compliance standards for the intended application before procurement.

Selection Notes

Select this component when a PNP configuration with a 22 kΩ base resistor is required. Ensure the operating voltage does not exceed the -50 V collector-emitter breakdown rating and that power dissipation limits are respected within the specified temperature range.

Part Context

This part belongs to the DDTA R1-only series of pre-biased transistors from Diodes Incorporated. It is designed as a complementary counterpart to NPN types within the DDTC series, offering a standardized solution for biasing requirements in compact surface-mount designs.

Replacement Considerations

Direct replacements include other DDTA124 variants with compatible pinouts and electrical characteristics. Verify package compatibility and resistor tolerance specifications when substituting with components from different manufacturers.
