DDTC143TUA-7

Overview

The DDTC143TUA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and a built-in biasing resistor (R1 only) with a nominal value of 4.7 kΩ. The device operates within a collector-emitter voltage range of up to 50 V and supports a maximum 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 gain-bandwidth product is typically 250 MHz. It is housed in a SOT323 package, complies with RoHS standards, and is halogen and antimony free.

Feature Summary

Epitaxial planar die construction for reliable performance
Built-in single biasing resistor simplifies circuit design
Surface mount package optimized for automated assembly processes
Environmentally compliant with lead-free, halogen-free, and antimony-free specifications

Applications

Switching applications in portable electronic devices
Driver circuits for low-power loads
Logic interface buffering between microcontrollers and peripheral components

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packing quantity and carrier type. Confirm that the component status remains active for production use. Ensure compliance with relevant environmental directives such as RoHS 3 and REACH requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact NPN solution with integrated base biasing is required. The 4.7 kΩ internal resistor value determines the input drive characteristics. Consider the SOT323 footprint constraints and the 200 mW power dissipation limit under your specific thermal management conditions.

Part Context

This part belongs to the DDTC (R1-ONLY SERIES) UA family produced by Diodes Incorporated. The series includes various resistor values ranging from 1 kΩ to 200 kΩ. The 'UA' designation indicates the SOT323 surface mount package configuration used for space-efficient PCB layouts.

Replacement Considerations

Direct substitutes within the same series include DDTC113TUA-7-F, DDTC123TUA-7-F, DDTC114TUA-7-F, DDTC124TUA-7-F, DDTC144TUA-7-F, DDTC115TUA-7-F, and their 10,000-unit reel variants. Verify resistor tolerance and package compatibility when cross-referencing.
