DDC115EU-7-F

Overview

The DDC115EU-7-F is an NPN pre-biased small signal dual surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and built-in biasing resistors, specifically R1 and R2 both at 100 kΩ nominal value. The device operates with a collector-emitter breakdown voltage of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 200 mW within an operating temperature range of -55°C to +150°C. Packaged in SOT363, it offers a transition frequency of 250 MHz and a minimum DC current gain (hFE) of 100.

Feature Summary

• Integrated dual biasing resistors simplify circuit design by reducing component count and PCB footprint.
• Automotive-grade qualification available through the DDC(XXXX)UQ variants for specific change control requirements.
• Compliant with RoHS 3 standards and defined as a halogen-free green device.

Applications

• Switching applications requiring high input impedance due to 100 kΩ base resistors.
• Driver circuits for logic interfaces where minimal base drive current is necessary.
• Automotive electronics utilizing AEC-Q101 qualified complementary PNP types from the same family.

Procurement Notes

Verify the exact ordering suffix against the manufacturer's active part list to ensure correct packaging and status. Confirm that the standard DDC115EU-7-F meets project requirements before selecting automotive-specific UQ variants. Check datasheet revision dates for updated electrical characteristics or mechanical dimensions prior to finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration with high-value 100 kΩ biasing resistors is required. Ensure the 50 V collector-emitter voltage rating aligns with the system supply limits. Consider the SOT363 package constraints regarding thermal dissipation and pad layout compatibility during the initial schematic capture phase.

Part Context

This component belongs to the DDC(XXXX)U series of pre-biased transistors designed for surface mount assembly. The 'U' suffix indicates the SOT363 package type. It serves as a compact alternative to discrete resistor-transistor networks, offering consistent electrical performance across manufacturing batches while maintaining low profile requirements.

Replacement Considerations

The DDC114EU-7-F provides identical packaging but utilizes 10 kΩ resistors instead of 100 kΩ. For automotive applications requiring specific change control, the DDC115EUQ-7-F variant is the designated upgrade path, though currently marked as Not Recommended for New Design.
