DDC114YU-7-F

Overview

The DDC114YU-7-F is a dual NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and integrates built-in biasing resistors within a compact SOT363 package. The device supports a maximum supply voltage of 50 V and a continuous collector current of 70 mA, with a peak output current capability of 100 mA. Power dissipation is rated at 200 mW, and the transition frequency reaches 250 MHz. Internal resistor values are nominally 10 kΩ for R1 and 47 kΩ for R2.

Feature Summary

• Integrates two NPN transistors with built-in biasing resistors to reduce external component count.
• Utilizes epitaxial planar die construction for reliable performance in surface mount applications.
• Compliant with RoHS directives and manufactured using halogen-free and antimony-free materials.

Applications

• General-purpose switching circuits requiring dual NPN logic control.
• Driver stages for low-power loads in consumer electronics.
• Interface circuits between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and availability status. Confirm that the component meets all required environmental standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in a minimal footprint. Ensure the design accounts for the 70 mA continuous collector current limit and verify that the 10 kΩ base resistor value aligns with the target drive voltage and load requirements.

Part Context

This part belongs to the DDC(XXXX)U series of pre-biased dual transistors from Diodes Incorporated. It shares the SOT363 package form factor with other variants in the family but differs in internal resistor ratios and current ratings. The 'YU' designation specifically indicates the 10 kΩ/47 kΩ resistor combination.

Replacement Considerations

The datasheet lists DDC114YUQ-7-F as Not Recommended for New Design (NRND), suggesting ADC114YUQ as the replacement. Verify electrical compatibility and pinout alignment before substituting any alternative components.
