DDC114EU-7

Overview

The DDC114EU-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=∞) to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage (VCEO) 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 gain-bandwidth product of 250MHz.

Feature Summary

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

Applications

• General-purpose switching applications
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

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

Selection Notes

Select this component when a dual NPN digital transistor with high input impedance and low saturation voltage is required. Ensure the application voltage does not exceed the 50V VCEO rating and that the total power dissipation remains within the 200mW limit considering ambient temperature derating curves provided in the datasheet.

Part Context

This component belongs to the DDC (xxxx) U series of pre-biased small signal transistors. It shares the SOT-363 package form factor with other variants in the family, differing primarily in internal resistor values and transistor polarity configurations. The series is designed for space-constrained surface-mount applications requiring integrated biasing solutions.

Replacement Considerations

Direct substitutes within the same series include DDC114TU-7 and DDC114YU-7, which share the SOT-363 package and dual NPN configuration but feature different internal resistor ratios. Verify pin compatibility and electrical ratings before substitution.
