ADTA113ZUAQ-13

Overview

The ADTA113ZUAQ-13 is a pre-biased NPN digital transistor manufactured by Diodes Incorporated, housed in an SOT-323 surface-mount package. It integrates a single NPN bipolar junction transistor with internal biasing resistors to simplify circuit design and reduce component count. The device is qualified under the AEC-Q101 standard for automotive applications. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -50 V, a continuous collector current of -100 mA, and a peak DC collector current of -100 mA. The power dissipation capability is rated at 330 mW, with an operating temperature range spanning from -55°C to +150°C.

Feature Summary

• Integrates NPN transistor with built-in biasing resistors to minimize external components and PCB space.
• AEC-Q101 qualified for reliability in demanding automotive electronic environments.
• Designed for high-speed switching applications with low saturation voltage characteristics.

Applications

• Automotive infotainment system logic interfaces
• General-purpose switching circuits in consumer electronics
• Driver circuits for LEDs and small loads

Procurement Notes

Verify the specific suffix '13' corresponds to the tape-and-reel packaging configuration as defined by the manufacturer's official documentation. Confirm that the AEC-Q101 qualification status is required for the target application, as this indicates automotive-grade reliability standards. Ensure compatibility with the SOT-323 footprint during the layout phase.

Selection Notes

Select this component when a compact NPN solution with integrated base resistance is needed for signal switching or level shifting. The AEC-Q101 qualification makes it suitable for automotive systems where long-term reliability is critical. Compare the 330 mW power dissipation rating against thermal constraints in dense assemblies.

Part Context

This part belongs to the ADTA series of pre-biased transistors from Diodes Incorporated. The series offers various resistor ratios and polarities to accommodate different logic interface requirements. The 'ZU' designation typically refers to the SOT-323 package style, while 'AQ' often denotes automotive qualification and specific material compliance.

Replacement Considerations

Direct substitutes may include other AEC-Q101 qualified NPN pre-biased transistors in SOT-323 packages from Diodes Incorporated, such as the ADTC113ZUAQ series, provided the internal resistor values and hFE characteristics match the original design requirements.
