DCX143ZU-13R-F

Overview

The DCX143ZU-13R-F is a 50V complementary pre-biased transistor from Diodes Incorporated, housed in an SOT-363 surface-mount package. It integrates NPN and PNP transistors with nominal bias resistors of 4.7 kΩ and 47 kΩ respectively. The device supports a maximum collector current of 100 mA and dissipates up to 200 mW of power. Operating temperatures range from -55°C to +150°C. The '13R' suffix indicates a 10,000-unit reel packing format.

Feature Summary

• Complementary NPN/PNP configuration with integrated biasing resistors
• Automated assembly compatible surface-mount design
• Lead-free and fully RoHS compliant construction

Applications

• Automotive applications requiring specific change control
• General-purpose switching circuits
• Driver circuits for low-power loads

Procurement Notes

Verify the ordering suffix against official documentation to confirm the specific packaging quantity and carrier type. Confirm that the component meets all applicable environmental directives and quality standards required for the intended manufacturing process before finalizing procurement orders.

Selection Notes

Select this part when a complementary pair with asymmetric bias ratios is required within a compact footprint. Ensure the 50V supply voltage rating and 100mA output current limits align with the circuit requirements. Verify thermal dissipation capabilities relative to the ambient operating temperature conditions.

Part Context

This component belongs to the DCX (XXXX) U series of 50V complementary pre-biased transistors. It shares the same physical package and general electrical characteristics as other variants in the family, distinguished primarily by the internal resistor values and specific marking codes assigned by the manufacturer.

Replacement Considerations

Publicly confirmed substitutes include ACX124EUQ and ACX114YUQ for related discontinued or not recommended for new design (NRND) variants within the same product family.
