DCX123JH-7

Overview

The DCX123JH-7 is a complementary NPN/PNP pre-biased small signal transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction with built-in biasing resistors and is housed in an SOT563 package. The device operates within a supply voltage range of ±50 V and supports a maximum output current of 100 mA per section, with a total power dissipation of 150 mW. Electrical characteristics include a collector-emitter breakdown voltage (BVCEO) of 50 V, an emitter-base breakdown voltage (BVEBO) of 5 V, and a typical gain-bandwidth product (fT) of 250 MHz. The component is fully RoHS compliant and halogen-free.

Feature Summary

• Complementary NPN/PNP configuration integrated into a single surface-mount package
• Epitaxial planar die construction for reliable switching performance
• Built-in biasing resistors simplify circuit design and reduce board space
• Totally lead-free and fully RoHS compliant with halogen and antimony-free green compound

Applications

• General-purpose switching applications requiring compact dual-transistor solutions

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration. Confirm that the SOT563 footprint matches your PCB layout requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure proper handling procedures are followed during assembly to maintain device integrity.

Selection Notes

Select this component when a complementary pair with integrated biasing is needed in a minimal footprint. Consider the 150 mW total power dissipation limit and thermal resistance values for heat management. Verify input voltage ranges against your logic levels to ensure proper saturation and cutoff behavior under operating conditions.
