DDTC115ECA-7-F

Overview

The DDTC115ECA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors where R1 equals R2, with a nominal resistance of 100 kOhms. The device utilizes epitaxial planar die construction and is housed in an SOT23 package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 200 mW. The DC current gain (hFE) has a minimum value of 82 at a collector current of 5 mA. The transition frequency is typically 250 MHz.

Feature Summary

• Integrated dual biasing resistors with equal nominal values to simplify circuit design
• Qualified to AEC-Q101 standards for high reliability applications
• Totally lead-free and fully RoHS compliant with halogen and antimony free green device construction

Applications

• Switching applications requiring integrated base drive components
• Automotive electronic systems meeting AEC-Q101 requirements
• General purpose digital logic interface circuits

Procurement Notes

Verify the specific ordering suffix matches the required packaging quantity and compliance level. The -7-F suffix indicates a standard reel size of 7 inches with 3,000 units per reel. Confirm that the AEC-Q101 qualification status aligns with project reliability specifications before finalizing procurement orders.

Selection Notes

Select this component when a single NPN transistor with matched internal biasing resistors is required. Ensure the 100 kOhm resistor value suits the input drive voltage and desired saturation levels. Verify that the SOT23 package dimensions fit the available PCB footprint and that the 200 mW power dissipation rating accommodates the thermal environment.

Part Context

This part belongs to the DDTC series of pre-biased transistors from Diodes Incorporated. The ECA suffix denotes the specific resistor configuration and package type within the family. It serves as a compact alternative to discrete resistor-transistor networks, reducing component count and board space in digital switching designs.

Replacement Considerations

Direct replacements must match the NPN polarity, 100 kOhm resistor values, and SOT23 package. Verify that any substitute component meets the same AEC-Q101 automotive qualification if required by the application. Check pinout compatibility to ensure correct connection of base, collector, and emitter terminals.
