DCX115EK-7-F

Overview

The DCX115EK-7-F is a dual complementary pre-biased transistor from Diodes Incorporated, housed in an SOT26 (SOT-363) surface-mount package. It integrates one NPN and one PNP epitaxial planar die with built-in biasing resistors of 100 kΩ each. The device supports a maximum supply voltage of 50 V and a continuous collector current of 100 mA per section. Total power dissipation is rated at 300 mW, with an operating temperature range spanning -55°C to +150°C. The component features a transition frequency of 250 MHz and complies with RoHS 3 standards.

Feature Summary

• Integrates NPN and PNP transistors with built-in biasing resistors for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Complies with RoHS 3 directives and is halogen-free

Applications

• General-purpose switching applications requiring complementary logic levels
• Driver circuits for low-power loads
• Interface circuits between digital logic and analog components

Procurement Notes

Verify the active status and compliance markings before procurement. Confirm that the SOT26 footprint matches the PCB layout requirements. Ensure the 100 kΩ resistor values align with the specific drive current needs of the target application. Check for any automotive qualification requirements if the end-use involves IATF 16949 certified facilities.

Selection Notes

Select this component when a complementary pair with matched 100 kΩ base resistors is required in a compact SOT26 package. Consider the 300 mW total power dissipation limit when designing thermal management strategies. Verify that the 50 V breakdown voltage meets the system's maximum supply requirements. Evaluate the 250 MHz transition frequency against the intended signal speeds.

Part Context

This part belongs to the DCX115 series of dual complementary pre-biased transistors. It shares the same internal configuration as other variants in the family but differs in resistor values and packaging suffixes. The 'EK' designation specifically indicates the 100 kΩ/100 kΩ resistor combination within the SOT26 case.
