DDC123JU-7-F

Overview

The DDC123JU-7-F is a dual NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 47 kΩ. The device operates within a supply voltage range up to 50 V and supports a continuous collector current of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 100, an emitter-base breakdown voltage of 5 V, and a transition frequency of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. The component is housed in a compact SOT-363 package.

Feature Summary

• Integrates dual NPN transistors with internal biasing resistors for simplified circuit design.
• Utilizes epitaxial planar die construction for reliable performance.
• Compliant with RoHS directives and halogen/antimony-free standards.

Applications

• Switching applications requiring integrated base drive components.
• Driver circuits for logic level translation or interface buffering.
• Automotive electronics utilizing AEC-Q101 qualified variants.

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details and reel size. Confirm that the selected variant meets all required environmental and quality certifications for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration with fixed 2.2 kΩ and 47 kΩ biasing resistors is required. Ensure the input voltage limits (-5V to +12V) align with the system logic levels. Verify that the SOT-363 footprint matches the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the DDC(XXXX)U series of NPN pre-biased dual transistors. It shares the same physical package and general electrical architecture as other members of the family, distinguished primarily by the specific resistance values of the integrated biasing network.

Replacement Considerations

Check for direct equivalents such as the ADC123JU series if the DDC123JU is not recommended for new designs. Verify pinout compatibility and resistor tolerance specifications before substituting with parts from other manufacturers.
