DCX114EH-7

Overview

The DCX114EH-7 is a complementary NPN/PNP pre-biased small signal transistor manufactured by Diodes Incorporated. It integrates built-in biasing resistors within an SOT563 case, featuring epitaxial planar die construction. The device supports a supply voltage of ±50 V and a maximum collector current of 100 mA. Total power dissipation is rated at 150 mW, with an operating temperature range from -55 °C to +150 °C. Both transistors utilize a 10 kΩ input resistor configuration. The component is lead-free, fully RoHS compliant, and halogen-free.

Feature Summary

• Integrates built-in biasing resistors for simplified circuit design
• Utilizes epitaxial planar die construction for reliability
• Complementary NPN and PNP configurations in a single package

Applications

• General-purpose switching applications
• Driver circuits requiring integrated biasing
• Low-voltage logic interface circuits

Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging details. Confirm that the requested quantity aligns with standard shipping formats such as tape and reel specifications. Ensure compliance with environmental directives including RoHS and halogen-free requirements prior to procurement.

Selection Notes

Select this component when a complementary pair with integrated biasing is required in a compact surface-mount footprint. Verify that the 10 kΩ internal resistor values meet the drive requirements of the target application. Ensure the thermal resistance and power dissipation limits are sufficient for the intended ambient temperature conditions.

Part Context

This part belongs to the DCX (xxxx) H series of complementary pre-biased transistors. It shares the SOT563 package and general electrical characteristics with other variants in the family, distinguished primarily by the specific resistance values of the integrated biasing network.

Replacement Considerations

Compatible substitutes include other DCX114 variants with identical 10 kΩ resistor ratios, such as DCX114TH-7 or DCX114YH-7, provided the pinout and package dimensions remain compatible.
