DDC114YU-7

Overview

The DDC114YU-7 is a dual NPN pre-biased small signal transistor from Diodes Incorporated, housed in an SOT-363 surface-mount package. It integrates two NPN transistors with built-in biasing resistors (R1=10kΩ, R2=47kΩ) to simplify circuit design and reduce component count. Key electrical ratings include a maximum collector-emitter voltage of 50V, continuous collector current of 100mA, and total power dissipation of 200mW. The device operates within a temperature range of -55°C to +150°C and features a minimum DC current gain of 68.

Feature Summary

• Dual NPN configuration with integrated biasing resistors for simplified switching applications
• Epitaxial planar die construction ensuring robust performance
• Lead-free and RoHS compliant manufacturing process

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Low-power digital signal processing

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm compliance requirements. The standard part number may require a specific suffix to denote lead-free or RoHS-compliant versions. Confirm packaging details such as tape and reel quantities directly with the supplier or official datasheets before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN solution with fixed internal biasing is required to minimize external resistor usage. Ensure the application voltage does not exceed the 50V collector-emitter rating and that thermal constraints allow for 200mW total dissipation. Verify that the 10kΩ input resistance aligns with the driving source capabilities.

Part Context

This component belongs to the DDC114 series of dual pre-biased transistors manufactured by Diodes Incorporated. The series offers various resistor ratio combinations and polarity options, including complementary PNP types. The DDC114YU variant specifically provides a 10kΩ base resistor and a 47kΩ emitter resistor configuration within the compact SOT-363 footprint.

Replacement Considerations

Complementary PNP versions are available within the same product family. Other variants in the DDC114 series offer different resistor ratios but maintain similar electrical characteristics and packaging.
