Overview
The ADTA113ZUAQ-7 is a PNP digital transistor manufactured by Diodes Incorporated, designed for surface-mount applications in the SOT-323-3 package. It integrates a single NPN transistor with built-in biasing resistors to simplify circuit design and reduce component count. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and a power dissipation (Pd) of 330 mW. The device features typical base resistor (R1) values of 1 kOhm and emitter-base resistor (R2) values of 10 kOhm, resulting in a resistance ratio of approximately 0.1. It operates within a temperature range of -55°C to +150°C and meets AEC-Q101 automotive qualification standards.
Feature Summary
- Integrated pre-bias configuration simplifies switching applications by eliminating external base drive components.
- Automotive-grade reliability ensured through AEC-Q101 qualification for harsh operating environments.
- Compact SOT-323-3 surface-mount package facilitates high-density PCB layout and automated assembly.
Applications
- Automotive electronic control units requiring robust switching performance.
- General-purpose logic level translation and interface circuits.
- Power management systems utilizing low-voltage DC-DC converters.
Procurement Notes
Verify the specific suffix 'Q' indicates AEC-Q101 automotive qualification status against the official manufacturer datasheet before procurement. Confirm that the SOT-323-3 package dimensions match the target PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles specified in the product documentation to maintain device integrity during assembly processes.
Selection Notes
Select this component when an automotive-qualified PNP digital transistor with integrated biasing is required. Compare the 1k/10k resistor ratio against alternative models if specific input impedance characteristics are critical. Verify that the 330 mW power dissipation rating suffices for the intended thermal environment and duty cycle conditions without exceeding maximum junction temperature limits.
Part Context
This part belongs to the ADTA113 series of pre-biased transistors from Diodes Incorporated. The 'Q' suffix typically denotes automotive grade compliance, distinguishing it from commercial variants like the DDTA113ZUA-7-F. It serves as a direct replacement for discrete resistor-transistor networks in space-constrained designs requiring standardized switching behavior.
Replacement Considerations
Direct substitutes include other AEC-Q101 qualified PNP digital transistors in SOT-323 packages with similar 1k/10k resistor ratios. Verify pinout compatibility and electrical parameters such as VCEO and IC ratings before substitution. Consider the DDTA113ZUA-7-F for non-automotive applications where automotive qualification is not mandatory.
