DCX124EK-7-F

Overview

The DCX124EK-7-F is a dual complementary pre-biased transistor manufactured by Diodes Incorporated. It integrates one NPN and one PNP transistor within a single SOT-26 (SC-74R) surface-mount package. The device features built-in biasing resistors, with both R1 and R2 specified at 22 kΩ. Key electrical ratings include a maximum collector-emitter voltage of 50 V for both polarities and a continuous collector current of 30 mA per section. Total power dissipation is rated at 300 mW, and the transition frequency is typically 250 MHz. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in biasing resistors in a compact SMD package
• Utilizes epitaxial planar die construction for reliable performance
• Compliant with RoHS standards and free from halogen and antimony

Applications

• General-purpose switching applications requiring complementary logic levels
• Driver circuits for low-power loads utilizing integrated biasing
• Automotive electronics compatible with IATF 16949 certified manufacturing processes

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific ordering suffix matches the required packaging quantity and compliance markings. Ensure all procurement activities adhere to applicable trade regulations and quality assurance protocols defined by the supplier.

Selection Notes

Select this component when a matched NPN/PNP pair with identical 22 kΩ base resistors is required. The SOT-26 package is suitable for space-constrained designs. Verify that the 30 mA output current rating meets the load requirements and that the 300 mW total power dissipation accommodates thermal constraints in the target application environment.

Part Context

This part belongs to the DCX(XXXX)K series of dual complementary pre-biased transistors produced by Diodes Incorporated. The series offers various resistor configurations within the SOT-26 package to support different logic drive requirements. The DCX124EK variant specifically provides symmetric 22 kΩ resistance values for both NPN and PNP sections.

Replacement Considerations

Direct functional substitutes within the same series include DCX123JK-7 and DCX114YK-7, though these feature different resistor values. Verify pinout compatibility and electrical parameter alignment before substitution.
