Overview
The ADTA143XUAQ-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction with built-in biasing resistors, specifically R1 at 4.7 kΩ and R2 at 10 kΩ. The device is qualified to AEC-Q101 standards for high reliability and is PPAP capable. It operates within a supply voltage range of -50 V and supports a maximum collector current of -100 mA. The component is housed in an SOT-323 package, suitable for automated assembly, and functions across a temperature range of -55°C to +150°C.
Feature Summary
- Integrated biasing resistors simplify circuit design by reducing component count.
- Qualified to AEC-Q101 standards for automotive applications.
- Totally lead-free and fully RoHS compliant.
- Surface mount package optimized for automated assembly.
Applications
- Automotive electronic systems requiring high reliability components.
- General-purpose switching applications utilizing surface mount technology.
- Circuit designs needing integrated biasing for simplified layouts.
Procurement Notes
Verify the specific ordering suffix (-7 or -13) to confirm reel size and quantity per reel, as these affect packaging logistics. Confirm that the automotive grade qualification aligns with project requirements. Ensure compliance with RoHS and halogen-free specifications if mandated by the end-use application. Check for PPAP capability needs during the procurement phase.
Selection Notes
Select this component when a PNP digital transistor with specific 4.7 kΩ input and 10 kΩ emitter-base resistance values is required. Consider the SOT-323 package dimensions for PCB layout constraints. Evaluate the thermal characteristics against the expected power dissipation in the target application environment.
Part Context
This part belongs to the ADTA series of pre-biased transistors from Diodes Incorporated. These devices integrate NPN or PNP transistors with internal biasing resistors to replace discrete resistor-transistor combinations. The ADTA143XUAQ variant specifically targets automotive markets due to its AEC-Q101 qualification.
Replacement Considerations
Consult official manufacturer documentation for direct pin-compatible substitutes. Verify electrical parameters such as gain-bandwidth product and saturation voltage when considering alternative brands or models.
