DCX143ZU-7-F

Overview

The DCX143ZU-7-F is a complementary pre-biased transistor array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It integrates one NPN and one PNP bipolar junction transistor with internal biasing resistors (R1 = 4.7 kΩ, R2 = 47 kΩ). The device supports a supply voltage of 50 V and handles continuous collector currents up to 100 mA per element. Key electrical parameters include a minimum DC current gain (hFE) of 100, a peak output current of 100 mA, and a power dissipation rating of 200 mW. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Complementary dual configuration integrating one NPN and one PNP transistor with integrated base biasing resistors for simplified circuit design.
• Surface-mount SOT-363 package designed for automated assembly processes.
• Halogen-free and antimony-free green device compliant with RoHS directives.

Applications

• Automotive applications requiring AEC-Q101 qualification and PPAP capability.
• General-purpose switching and logic interface circuits.
• Driver stages for low-power loads requiring complementary signal inversion.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size and tape width. Confirm that the component meets all applicable environmental compliance standards required for the target market before finalizing procurement orders.

Selection Notes

Select this part when a compact solution requires both NPN and PNP switching capabilities with fixed bias ratios. Ensure the application voltage does not exceed the 50V limit and that thermal management accommodates the 200mW dissipation rating within the specified operating temperature range.

Part Context

This component belongs to the DCX(XXXX)U series of 50V complementary pre-biased transistors. It shares the same SOT-363 footprint and general electrical characteristics as other members of the family, differentiated primarily by the nominal values of the integrated base resistors R1 and R2.

Replacement Considerations

Publicly confirmed substitutes are not identified in the provided datasheet. Verify compatibility with alternative components based on matching pinout, voltage ratings, and resistor values.
