DDC114EU-7-F

Overview

The DDC114EU-7-F is a dual NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It integrates two independent NPN transistors with built-in biasing resistors in an SOT363 package. The device features a collector-emitter breakdown voltage (BVCEO) of 50 V and a continuous collector current (IO) of 50 mA per element, with a peak output current of 100 mA. Power dissipation is rated at 200 mW total, limited to 150 mW per element. The typical input resistor values are R1 = 10 kΩ and R2 = 10 kΩ. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Integrates dual NPN transistors with built-in biasing resistors for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Compliant with RoHS standards and halogen/antimony-free green device specifications

Applications

• General-purpose switching applications
• Driver circuits requiring integrated biasing
• Low-power digital logic interfacing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and status. The '7' suffix indicates a standard reel size, while other suffixes may denote different quantities or tape widths. Confirm that the component meets all required environmental compliance standards for the intended application before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration with fixed internal biasing is required to reduce external component count. Ensure the 50 mA continuous current rating per element is sufficient for the load. Verify that the 10 kΩ internal resistor values align with the driving source capabilities and desired switching speeds. Consider the SOT363 footprint constraints during PCB layout.

Part Context

This part belongs to the DDC(XXXX)U series of pre-biased transistors from Diodes Incorporated. It shares the same SOT363 package and general electrical characteristics as other variants in the family, differing primarily in the specific resistance values of the integrated R1 and R2 components. The EU suffix denotes the specific 10kΩ/10kΩ resistor combination within this product line.

Replacement Considerations

Direct substitutes include other DDC114 variants with identical resistor ratios if pinout compatibility is maintained. For automotive applications, consider the AEC-Q101 qualified ADC114EUQ series as a recommended replacement for the NRND DDC114EUQ-7-F.
