DDTA123ECA-7-F

Overview

The Diodes Incorporated DDTA123ECA-7-F is a PNP pre-biased small signal surface mount transistor housed in an SOT-23 package. It features built-in biasing resistors where R1 equals R2, with a nominal resistance of 2.2kΩ. The device supports a supply voltage (VCC) of -50V and a continuous collector current of -100mA. Power dissipation is rated at 200mW, with a thermal resistance from junction to ambient air of 625°C/W. The minimum DC current gain (hFE) is specified as 20, and the transition frequency (fT) reaches 250MHz. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Integrates dual biasing resistors with equal values to simplify circuit design
• Constructed using epitaxial planar die technology for reliability
• Qualified to AEC-Q101 standards for high-reliability automotive applications
• Manufactured with lead-free, halogen-free, and antimony-free green materials

Applications

• Automotive electronic systems requiring AEC-Q101 compliance
• General-purpose switching circuits utilizing single NPN/PNP configurations
• Driver stages for logic-to-power interface conversion

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS 3 and AEC-Q101 compliance status prior to integration. Ensure storage conditions adhere to J-STD-020 moisture sensitivity level 1 requirements. Validate marking codes against official ordering information tables to prevent counterfeit substitution.

Selection Notes

Select this model when a PNP digital transistor with 2.2kΩ internal biasing is required. Compare against complementary NPN types within the DDTC series if polarity inversion is needed. Evaluate thermal constraints based on the 625°C/W junction-to-ambient resistance value during PCB layout planning.

Part Context

This component belongs to the DDTA (R1=R2 Series) CA family of pre-biased transistors. It shares electrical characteristics with other variants in the series that differ only in resistor values, such as the DDTA143ECA or DDTA114ECA. The suffix '-7-F' indicates reel packaging with 3,000 units per reel.

Replacement Considerations

Direct substitutes include other DDTA123ECA variants from Diodes Incorporated. Complementary NPN equivalents are available in the DDTC123 series. Verify pinout compatibility and absolute maximum ratings before substituting.
