DCX143EU-7R-F

Overview

The DCX143EU-7R-F is a dual pre-biased digital transistor manufactured by Diodes Incorporated, featuring an NPN/PNP configuration within a surface-mount SOT-363-6 package. It integrates internal biasing resistors with typical values of 4.7 kOhms and a resistor ratio of 1. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, continuous collector current of 100 mA, and peak DC collector current of 100 mA. The device offers a minimum DC current gain (hFE) of 100 and operates up to a maximum frequency of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C.

Feature Summary

• Integrates dual NPN and PNP transistors with built-in biasing resistors for simplified circuit design.
• Optimized for high-speed switching applications with a transition frequency of 250 MHz.
• Provides robust performance across a wide industrial temperature range.

Applications

• General-purpose switching in portable consumer electronics.
• Driver circuits for low-power loads in embedded systems.
• Logic level translation and interface buffering in digital circuits.

Procurement Notes

Verify the specific suffix '7R-F' against the manufacturer's official datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with standard SMT assembly processes for the SOT-363 footprint. Cross-reference RoHS compliance documentation directly with Diodes Incorporated to meet regulatory requirements for your target market.

Selection Notes

Select this component when a compact dual solution combining both NPN and PNP functions is required. The integrated biasing network reduces external component count compared to discrete transistor pairs. Verify that the 50 V voltage rating and 100 mA current capacity align with the load requirements of the specific application circuit.

Part Context

This part belongs to the DCX series of pre-biased digital transistors from Diodes Incorporated. It serves as a dual-channel alternative to single-transistor digital arrays like the DDTC series. The SOT-363 package allows for space-efficient PCB layouts in dense electronic designs requiring multiple switching elements.

Replacement Considerations

Direct pin-compatible substitutes may include other dual NPN/PNP digital transistors in SOT-363 packages, such as the DCX143ZU-7-F or DCX143EU-7-F, provided electrical ratings match. Always verify resistor values and hFE characteristics before substitution.
