DDTC123TUA-7-F

Overview

The DDTC123TUA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features a built-in biasing resistor (R1) with a nominal value of 2.2 kΩ and operates within a collector-emitter voltage range up to 50 V. The device supports a maximum continuous collector current of 100 mA and dissipates up to 200 mW of power. Packaged in an SOT-323 (SC-70) housing, it offers a gain-bandwidth product of 250 MHz and a DC current transfer ratio (hFE) ranging from 100 to 600 at IC = 1mA, VCE = 5V.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated single biasing resistor simplifies circuit design
• Surface mount package optimized for automated assembly processes
• Fully compliant with RoHS directives and free of halogens and antimony

Applications

• General-purpose switching applications
• Driver circuits for logic interfaces
• Low-power signal amplification stages

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packing quantity and carrier specifications. Confirm that the component status remains active for new designs. Ensure compliance with relevant environmental regulations such as RoHS 3 and REACH requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN solution with integrated base resistance is required. The 2.2 kΩ internal resistor value suits standard logic level driving scenarios. Consider the SOT-323 footprint constraints and thermal dissipation limits relative to the application's ambient temperature conditions.

Part Context

This part belongs to the DDTC R1-only series designed for space-saving applications. It serves as the NPN counterpart to the DDTA PNP series. The 'UA' suffix indicates the SOT-323 package type, while '-7-F' denotes the 3,000-unit reel packaging format.

Replacement Considerations

Direct substitutes include other DDTC123TUA variants with different resistor values or alternative manufacturers offering equivalent NPN pre-biased transistors in the SOT-323 package. Verify pinout compatibility and electrical parameters before substitution.
