DCX114YK-7-F

Overview

The DCX114YK-7-F is a dual complementary pre-biased transistor manufactured by Diodes Incorporated. It integrates an NPN and a PNP transistor within a single SOT26 surface-mount package, featuring built-in biasing resistors to simplify circuit design. The device utilizes epitaxial planar die construction and is fully lead-free and RoHS compliant. Key electrical specifications include a maximum supply voltage of 50V for both sections, a total power dissipation of 300mW, and an operating temperature range from -55°C to +150°C. The specific resistor configuration consists of R1 at 10kΩ and R2 at 47kΩ.

Feature Summary

• Integrates NPN and PNP transistors with built-in biasing resistors in a compact SOT26 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
• Digital interface buffering where space-saving dual configurations are required

Procurement Notes

Verify the current manufacturing status before procurement, as the datasheet lists this part number as obsolete. Confirm availability through authorized distributors or check for active replacement series if long-term supply stability is required for production. Ensure compliance with environmental directives relevant to your region.

Selection Notes

Select this component when a complementary pair with fixed 10kΩ and 47kΩ biasing ratios is needed. Verify that the 50V supply voltage and 300mW thermal dissipation limits meet the application requirements. Consider the SOT26 footprint constraints during PCB layout planning.

Part Context

This component belongs to the DCX (XXXX) K series of dual complementary pre-biased transistors. The 'Y' suffix indicates the specific internal resistor values of 10kΩ and 47kΩ. The '-7-F' suffix denotes the reel packaging format and lead-free compliance. This series is designed to replace discrete resistor-transistor networks.

Replacement Considerations

The datasheet explicitly identifies the DCX114YK-7-F as Obsolete. Engineers should evaluate alternative part numbers within the same DCX family or contact Diodes Incorporated directly for recommended replacements suitable for new designs.
