DDTA114TCA-7-F

Overview

The DDTA114TCA-7-F is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT23 package. It features a single built-in biasing resistor (R1) with a nominal value of 10 kOhms and a tolerance of ±30%. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, with a thermal resistance of 625 °C/W. DC current gain (hFE) ranges from 100 to 600 at IC = -1mA. Operating temperature spans from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated single biasing resistor simplifies circuit design
• Totally lead-free and fully RoHS compliant
• Halogen and antimony free green device

Applications

• General-purpose switching applications
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the reel packaging configuration detailed in the manufacturer's documentation. Confirm that the component meets the required environmental standards, including RoHS 3 compliance and halogen-free specifications, before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with a 10 kOhm base resistor is required. Ensure the application voltage does not exceed -50 V and the current remains within the -100 mA limit. Consider the thermal resistance of 625 °C/W for heat dissipation planning in enclosed environments.

Part Context

This part belongs to the DDTA(R1-ONLY) series, which includes various resistor values ranging from 1kΩ to 200kΩ. It is the PNP counterpart to the DDTC NPN series. The 'CA' suffix indicates the SOT23 package type. Other variants in the series include DDTA113TCA through DDTA125TCA with different resistor values.

Replacement Considerations

Direct substitutes within the same family include DDTA113TCA-7-F (1kΩ), DDTA124TCA-7-F (22kΩ), and DDTA144TCA-7-F (47kΩ). For NPN equivalents, consider the DDTC114TCA-7-F. Verify pinout compatibility and electrical ratings match the original design requirements.
