ADTA113ZCAQ-7

Overview

The ADTA113ZCAQ-7 is a PNP digital transistor manufactured by Diodes Incorporated, designed for surface-mount applications. It integrates a single NPN transistor with bias resistors in an SOT-523 package. Key electrical parameters include a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device features a typical base resistor of 1kΩ and an emitter-base resistor of 10kΩ, resulting in a resistance ratio of 0.1. It operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 150mW. The component meets AEC-Q101 automotive qualification standards.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards for robust performance in vehicle electronics.
• Integrated pre-bias configuration simplifies circuit design by combining a PNP transistor with internal base and emitter-base resistors.
• Compact SOT-523 surface-mount package enables efficient space utilization on high-density printed circuit boards.

Applications

• Automotive logic level shifting and signal switching circuits
• General-purpose switching applications in consumer electronics
• Driver circuits for low-power loads requiring pre-biased control

Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q101 automotive qualification when sourcing. Confirm package type matches SOT-523 requirements for PCB layout. Check manufacturer documentation for any recent product change notifications regarding manufacturing sites or materials. Ensure compatibility with automated pick-and-place equipment due to the small form factor.

Selection Notes

Select this component for designs requiring a PNP digital transistor with integrated biasing in a compact footprint. The AEC-Q101 certification makes it suitable for automotive environments where higher reliability is mandated compared to standard commercial grades. Consider the 1kΩ input resistance for driving capabilities and ensure the 150mW power dissipation limit accommodates the thermal conditions of the application.

Part Context

This part belongs to the ADTA113 series of pre-biased transistors from Diodes Incorporated. The 'A' prefix typically denotes automotive qualification, while 'DTA' indicates a dual-transistor or pre-biased configuration, though this specific variant is a single PNP unit. It serves as a specialized alternative to discrete resistor-transistor combinations, offering reduced board space and simplified assembly processes in modern electronic systems.

Replacement Considerations

Direct substitutes may include other AEC-Q101 qualified PNP digital transistors in SOT-523 packages with similar 1kΩ/10kΩ resistor ratios. Verify pinout compatibility and electrical ratings against alternatives such as DDTA113ZCAQ-7 if available from the same manufacturer or other qualified suppliers.
