Overview
The DDC124EU-7-F is an NPN pre-biased small signal dual surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and integrated biasing resistors within a SOT363 package. The device provides a supply voltage of 50 V, continuous collector current of 30 mA per element, and peak output current of 100 mA. Power dissipation is rated at 200 mW with a thermal resistance of 625 °C/W. Built-in resistors R1 and R2 are both 22 kΩ nominal. Transition frequency reaches 250 MHz, and the DC current gain ranges from 56 to 80 depending on operating conditions.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated biasing resistors simplify circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free green device
Applications
- General purpose switching applications
- Driver circuits for logic interfaces
- Low power amplification stages
Procurement Notes
Verify the exact part number suffix against official distributor catalogs before ordering. Confirm that the specific reel size and tape width match your automated assembly equipment requirements. Ensure compliance with local environmental regulations regarding halogen and antimony content if required by your manufacturing standards.
Selection Notes
Select this component when a dual NPN configuration with fixed internal biasing is required in a compact footprint. Compare the 22 kΩ resistor values against alternative models like the DDC144EU or DDC114YU if different input impedance characteristics are needed. Verify that the 30 mA continuous current rating meets the load requirements of your specific application design.
Part Context
This component belongs to the DDC (XXXX) U series of pre-biased transistors from Diodes Incorporated. The series includes various configurations with different resistor combinations and packaging options. The DDC124EU variant specifically utilizes the SOT363 package and standard 22 kΩ resistors for both base and emitter connections.
Replacement Considerations
Direct substitutes include other DDC124 variants such as DDC124EUQ-7-F, though the latter is marked as Not Recommended for New Design. Alternative packages or resistor values within the same family may require schematic adjustments.
