Overview
The ADTA124ECAQ-13 is a PNP pre-biased transistor in an SOT23 package, featuring built-in biasing resistors with R1 = R2 = 22kΩ. It operates with a supply voltage of -50V and a maximum collector current of -100mA. The device provides a minimum DC current gain (hFE) of 56 at -5mA output current. Thermal characteristics include a power dissipation of 310mW and a junction-to-ambient thermal resistance of 403°C/W. Operating and storage temperatures range from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Built-in biasing resistors eliminate external input components
- AEC-Q101 qualified and PPAP capable for automotive applications
- Manufactured in IATF 16949 certified facilities
Applications
- Automotive interface circuits
- Driver applications requiring specific change control
- General-purpose switching and logic inversion
Procurement Notes
Verify the ordering suffix '-13' corresponds to the 10,000-unit reel packing quantity as specified in the Diodes Incorporated datasheet. Confirm that the AEC-Q101 qualification and PPAP capability requirements align with your specific automotive project standards before finalizing procurement.
Selection Notes
Select this component when a PNP digital transistor with equal internal biasing resistors (R1=R2=22kΩ) is required. Ensure the -50V supply voltage rating and -100mA collector current capacity meet the circuit demands. Verify compatibility with surface-mount SOT23 assembly processes and check if AEC-Q101 qualification is mandatory for the target application.
Part Context
This part belongs to the ADTA series of pre-biased transistors manufactured by Diodes Incorporated. It is specifically designed for automotive environments, distinguishing itself through AEC-Q101 qualification and PPAP capability. The standard 'ADTA124ECAQ' variant is available in different packaging options, with the '-13' suffix indicating a 10,000-unit reel.
Replacement Considerations
Check for other Diodes Incorporated parts with similar resistor ratios and voltage ratings. Verify pinout compatibility and electrical parameters against alternative suppliers' equivalents to ensure functional interchangeability without redesign.
