ADTA143XUAQ-13

Overview

The ADTA143XUAQ-13 is a single PNP digital pre-bias transistor manufactured by Diodes Incorporated. It integrates internal bias resistors within an SOT-323-3 surface-mount package to simplify circuit design. The device features a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -70 mA, with a peak DC collector current rating of -100 mA. Power dissipation is specified at 330 mW. The component meets AEC-Q101 automotive qualification standards and operates across a temperature range from -55°C to +150°C. It exhibits a minimum DC current gain (hFE) of 68 and a typical resistor ratio of 20%.

Feature Summary

• Integrated pre-bias network reduces external component count and board space requirements.
• Automotive-grade reliability certified under the AEC-Q101 standard for robust performance.
• Enhancement mode operation ensures defined off-state characteristics for stable switching.

Applications

• Switching applications in automotive electronic control units.
• Driver circuits for low-power loads in industrial systems.
• Logic level translation interfaces between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific suffix '13' corresponds to the required tape-and-reel packaging configuration during sourcing. Confirm that the AEC-Q101 qualification status aligns with project reliability requirements. Ensure the SOT-323-3 footprint matches the target PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a PNP digital transistor with automotive certification is required. The -50 V rating suits general low-voltage switching tasks. Verify that the -70 mA continuous current capability meets load demands. Consider the SOT-323-3 package size if space optimization is critical compared to larger packages like SOT-23.

Part Context

This part belongs to the ADTA series of NPN/PNP digital transistors from Diodes Incorporated. The 'A' indicates PNP polarity, while '143' denotes the specific internal resistor ratio configuration. The 'XU' prefix typically identifies the SOT-323 package variant within the manufacturer's catalog structure.

Replacement Considerations

Cross-reference with other AEC-Q101 qualified PNP digital transistors in the SOT-323 package. Verify matching VCEO, IC ratings, and hFE specifications. Ensure equivalent internal resistor ratios to maintain circuit timing and drive characteristics without redesign.
