DDTA114TCA-7

Overview

The DDTA114TCA-7 is a PNP pre-biased transistor from the R1-only series, housed in an SOT23 package. It integrates a single base resistor (R1) with a nominal value of 10 kΩ. The device features a collector-emitter breakdown voltage (BVCEO) of -50 V and a maximum continuous collector current (IC) of -100 mA. Power dissipation is rated at 200 mW, with a thermal resistance (RθJA) of 625 °C/W. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = -1 mA and VCE = -5 V. The gain-bandwidth product (fT) is typically 250 MHz. Operating and storage temperatures span from -55°C to +150°C.

Feature Summary

• Integrates a single built-in biasing resistor (R1 only) for simplified circuit design.
• Utilizes epitaxial planar die construction for reliable performance.
• Comes in a compact SOT23 surface-mount package.
• Manufactured as a halogen- and antimony-free 'Green' device compliant with RoHS directives.

Applications

• General-purpose switching applications
• Driver circuits for small signal loads
• Logic interface buffering

Procurement Notes

Verify the specific ordering suffix against official documentation, as variations exist between standard and automotive-grade versions. Confirm availability status directly with Diodes Incorporated or authorized distributors, as lead times and stock levels fluctuate. Ensure compliance with environmental regulations such as RoHS 3 and REACH requirements relevant to your region before finalizing procurement.

Selection Notes

Select this component when a PNP digital transistor with a 10 kΩ base resistor is required in an SOT23 footprint. Verify that the -50 V collector-emitter voltage and -100 mA current ratings meet the application's electrical demands. Consider the thermal resistance and power dissipation limits if operating in high-temperature environments or with significant duty cycles.

Part Context

This part belongs to the DDTA R1-only series, which includes various resistor values ranging from 1 kΩ to 200 kΩ. The 'CA' suffix denotes the SOT23 package type. Complementary NPN types are available under the DDTC series. The device is designed for general electronic applications, with specific automotive variants requiring separate qualification inquiries.

Replacement Considerations

Direct substitutes within the same series include DDTA113TCA-7-F (1 kΩ), DDTA124TCA-7-F (22 kΩ), and DDTA144TCA-7-F (47 kΩ). For complementary NPN functionality, consider the DDTC114TCA-7 series. Always verify pinout compatibility and electrical parameters before substitution.
