Overview
The ADTA144VCAQ is a PNP pre-biased small-signal surface-mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrated biasing resistors, specifically R1 at 47kΩ and R2 at 10kΩ. The device is rated for a supply voltage of -50V and a maximum collector current of -100mA. It operates within a temperature range of -55°C to +150°C and dissipates up to 310mW. Qualified under AEC-Q101 standards, it utilizes an SOT-23 package with matte tin plated leads.
Feature Summary
- Built-in biasing resistors enable inverter circuit configuration without external input components.
- AEC-Q101 qualified and PPAP capable for automotive applications requiring specific change control.
- Totally lead-free and fully RoHS compliant with halogen and antimony-free green device construction.
Applications
- Automotive electronic systems requiring qualified discrete semiconductors
- Inverter circuits utilizing built-in biasing resistors
- General-purpose switching applications in surface-mount designs
Procurement Notes
Verify the specific ordering suffix when purchasing. The ADTA144VCAQ-13 variant indicates a 10,000-piece reel packing quantity, whereas the -7 suffix denotes a 3,000-piece reel. Confirm that the required packaging matches the project needs before finalizing orders. Ensure compliance with IATF 16949 manufacturing facility requirements if automotive qualification is mandatory.
Selection Notes
Select this component for designs requiring a PNP digital transistor with a 47kΩ base resistor and a 10kΩ emitter resistor. The SOT-23 package suits space-constrained layouts. Verify thermal derating requirements against the 403 °C/W junction-to-ambient resistance value for FR-4 PCB mounting conditions.
Part Context
This part belongs to the ADTA144 series of PNP pre-biased transistors from Diodes Incorporated. It shares the same electrical characteristics as other variants in the family but differs in packaging quantities and specific automotive qualification status. The VCAQ designation identifies the specific tape and reel configuration and quality level.
Replacement Considerations
The DTA144EUAFRA is listed as a similar level replacement with the same pinout and package. However, verify that the substitute meets the specific AEC-Q101 and PPAP requirements mandated for the original application.
FAQ
What are the nominal values of the built-in biasing resistors?
The internal circuit includes a base resistor (R1) of 47kΩ and an emitter resistor (R2) of 10kΩ.
Is this component suitable for high-temperature environments?
Yes, the operating and storage temperature range extends from -55°C to +150°C.
What does the '2M2' marking on the device indicate?
The '2M2' marking serves as the product type code for the ADTA144VCAQ in the SOT-23 package.
