ADTA144EUAQ-7

Overview

The ADTA144EUAQ-7 is a PNP pre-biased transistor manufactured by Diodes Incorporated in an SOT323 surface-mount package. It integrates built-in biasing resistors (R1 and R2, both nominally 47 kΩ) to simplify circuit design. The device features a maximum supply voltage of -50 V and a continuous collector current of -100 mA. It operates within a temperature range of -55°C to +150°C with a power dissipation rating of 330 mW. Qualified under AEC-Q101/200 standards for automotive applications, it offers a transition frequency of 250 MHz and a minimum DC current gain of 68.

Feature Summary

• Epitaxial planar die construction with integrated biasing resistors
• AEC-Q101 qualified and PPAP capable for automotive use
• Totally lead-free and fully RoHS compliant
• Halogen and antimony free green device

Applications

• Automotive electronic circuits requiring specific change control
• General-purpose switching applications
• Driver circuits for low-power loads

Procurement Notes

Verify the component against official datasheet DS38946 Rev. 2-2 specifications before integration. Confirm that the ordering suffix '-7' corresponds to the 3,000-unit reel packaging format. Ensure compliance with automotive quality requirements if deploying in vehicle systems, as this part is manufactured in IATF 16949 certified facilities.

Selection Notes

Select this component when a compact PNP solution with integrated base and emitter resistors is required. The SOT323 package suits automated assembly processes. Verify input voltage limits (+10V to -40V) and output current constraints (-30mA) against the specific application load requirements to ensure operation within absolute maximum ratings.

Part Context

This part belongs to the ADTA144 series of pre-biased transistors from Diodes Incorporated. It is specifically designed for automotive environments due to its AEC-Q101 qualification and PPAP capability. The 'EUAQ' designation indicates the specific pinout, resistor values, and automotive-grade manufacturing process.

Replacement Considerations

The DTA144EU3HZGT106 is listed as a similar level replacement with the same pinout and package. Verify electrical characteristics and thermal resistance parameters match the original design requirements before substitution.
