DDTC143TCAQ-13-F

Overview

The DDTC143TCAQ-13-F is an NPN pre-biased transistor from Diodes Incorporated, housed in a surface-mount SOT23 package. It integrates a single built-in biasing resistor (R1) with a nominal value of 4.7 kΩ and a tolerance of ±30%. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA, with a power dissipation rating of 200 mW. It features a minimum DC current gain (hFE) of 100 at IC = 1 mA and operates within a temperature range of -55°C to +150°C. This component is AEC-Q101 qualified for automotive applications.

Feature Summary

• Built-in biasing resistors allow for simplified circuit design by eliminating the need for external input resistors.
• AEC-Q101 qualification ensures suitability for automotive applications requiring specific change control.
• Epitaxial planar die construction provides robust performance characteristics.
• Totally lead-free and fully RoHS compliant, meeting environmental standards.

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components
• Inverter circuits utilizing integrated biasing
• General-purpose switching applications

Procurement Notes

Verify that the ordering suffix '-13-F' corresponds to the 10,000-unit reel packaging configuration as specified in the manufacturer's documentation. Confirm compliance with automotive quality requirements if the application demands AEC-Q101 qualification and PPAP capability. Ensure the procurement channel is authorized to guarantee product authenticity and adherence to standard terms and conditions.

Selection Notes

Select this part when a 4.7 kΩ base resistor is required for NPN switching applications. The SOT23 package offers a compact footprint suitable for space-constrained designs. Consider the 200 mW power dissipation limit and the -55°C to +150°C operating range to ensure thermal adequacy. Verify that the 100 mA collector current meets the load requirements of the intended circuit.

Part Context

This component belongs to the DDTC (R1-ONLY SERIES) CA family, which includes various NPN pre-biased transistors with different resistor values. The 'Q' suffix indicates automotive qualification, while the '13' suffix denotes the specific tape and reel quantity. Complementary PNP types are available in the DDTA series.

Replacement Considerations

Direct substitutes include other DDTC143TCA variants with identical electrical specifications but different packaging quantities, such as DDTC143TCAQ-7-F. Non-automotive equivalents like DDTC143TCA-7-F may be considered if AEC-Q101 qualification is not required.
