ADTA114EUAQ-13

Overview

The ADTA114EUAQ-13 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 10 kΩ. The device operates within a supply voltage range of -50 V and supports a maximum collector current of -100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 30 at -5V/-5mA, an output voltage of -0.1 V typical at -10mA/-0.5mA, and a transition frequency of 250 MHz. Power dissipation is rated at 330 mW, with an operating temperature range from -55°C to +150°C. It is housed in an SOT-323 package.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design
• Qualified to AEC-Q101 standards for automotive applications
• Totally lead-free and fully RoHS compliant

Applications

• Automotive electronic systems requiring high reliability
• General-purpose switching applications
• Driver circuits for low-power loads

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the 10,000 units per reel packaging configuration as defined in the manufacturer's documentation. Confirm that the component meets AEC-Q101 qualification requirements if intended for automotive use. Ensure compliance with RoHS and halogen-free specifications during procurement to align with project environmental standards.

Selection Notes

Select this component when a PNP digital transistor with 10kΩ base and emitter resistors is required in an SOT-323 package. Consider the -50V collector-emitter voltage and -100mA continuous current limits for load compatibility. Verify thermal management capabilities given the 330mW power dissipation rating in surface mount applications.

Part Context

This part belongs to the ADTA114 series of pre-biased transistors from Diodes Incorporated. The 'EUAQ' designation indicates the SOT-323 package and AEC-Q101 automotive qualification. The suffix '-13' specifies the tape and reel quantity of 10,000 units, distinguishing it from other packaging options like the '-7' variant which contains 3,000 units per reel.

Replacement Considerations

Direct substitutes within the same family include ADTA114EUAQ-7, which shares identical electrical characteristics but differs in packaging quantity (3,000 vs 10,000 units per reel). Other variants such as ADTA114YUAQ-13 offer different resistor ratios and should be evaluated for functional equivalence before substitution.
