Overview
The ADTA144EUAQ-13 is a PNP pre-biased transistor in an SOT-323 package. It features built-in biasing resistors (R1 and R2) of 47 kΩ each. The device has a maximum collector-emitter voltage (VCC) of -50 V and a continuous collector current (IC) of -100 mA. Power dissipation is rated at 330 mW, with a transition frequency (fT) of 250 MHz. DC current gain (Gl) is specified at a minimum of 68. Operating temperature range spans from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Built-in biasing resistors simplify circuit design
- AEC-Q101 qualified for automotive applications
- Totally lead-free and fully RoHS compliant
Applications
- Automotive electronic systems requiring AEC-Q101 qualification
- General-purpose switching applications
- Driver circuits for low-current loads
Procurement Notes
Verify the ordering suffix '-13' corresponds to the 10,000-unit reel quantity as documented in the manufacturer's ordering information. Confirm that the specific revision of the datasheet matches the production batch requirements. Ensure compliance with IATF 16949 manufacturing standards if automotive change control protocols are mandated by the end application.
Selection Notes
Select this component when a PNP digital transistor with integrated 47 kΩ base and emitter resistors is required. The SOT-323 package is suitable for space-constrained surface mount designs. Consider the -50 V supply voltage limit and -100 mA current capability during circuit planning. Verify thermal resistance constraints for high-duty cycle operations.
Part Context
This part belongs to the ADTA series of pre-biased transistors manufactured by Diodes Incorporated. The 'EUAQ' designation indicates automotive-grade qualification under AEC-Q101 standards. The suffix '-13' specifies the tape and reel packaging configuration containing 10,000 units per reel, distinct from the '-7' variant which contains 3,000 units.
Replacement Considerations
Direct pin-compatible replacements within the same family include ADTA144EUAQ-7, which shares identical electrical characteristics but differs in packaging quantity.
