ACX143ZUQ-13R

Bipolar Transistor Arrays, Pre-Biased Overview

The ACX143ZUQ-13R is a small signal complementary pre-biased dual transistor manufactured by Diodes Incorporated. It integrates an NPN and a PNP transistor within a single SOT-363 package, featuring built-in biasing resistors with nominal values of R1 = 4.7 kΩ and R2 = 47 kΩ. The device is qualified to AEC-Q101 standards for automotive applications. Electrical specifications include a maximum supply voltage of ±50 V, a continuous collector current of ±100 mA, and a total power dissipation of 270 mW at +25°C. The gain-bandwidth product (fT) is typically 250 MHz, and the operating temperature range spans from -55°C to +150°C.

Bipolar Transistor Arrays, Pre-Biased Procurement Notes

Verify that the specific ordering suffix matches the required reel quantity. The -13R suffix indicates a 10,000-unit reel size, whereas the -7R variant corresponds to 3,000 units. Confirm that the components are sourced through authorized distribution channels to ensure authenticity and adherence to quality standards. Check for PPAP capability requirements if the application involves automotive manufacturing processes.

Bipolar Transistor Arrays, Pre-Biased Selection Notes

Select this component when a complementary pair of pre-biased transistors is needed in a minimal footprint. The SOT-363 package accommodates both NPN and PNP sections with integrated base resistors. Ensure the design accounts for the 270 mW total power dissipation limit and the ±50 V voltage ratings. Verify that the 4.7 kΩ input resistance aligns with the driving source capabilities and desired switching speeds.

Bipolar Transistor Arrays, Pre-Biased Part Context

This part belongs to the ACX143 series of small signal complementary pre-biased dual transistors. It shares functional similarities with other Diodes Incorporated models like the DCX143 and DDTC143 families but is distinctively characterized by its AEC-Q101 qualification for automotive use. The device serves as a direct replacement for discrete resistor-transistor networks in space-constrained designs.

Bipolar Transistor Arrays, Pre-Biased Replacement Considerations

For non-automotive applications, the DCX143ZU-7-F or DCX143EU-7-F may serve as functional equivalents. For single-channel requirements, consider the ADTA143ZUAQ-7 or DDTC143ZUA-7-F. Verify pinout compatibility and thermal characteristics before substitution.
