ADTA114EUAQ-7

Overview

The ADTA114EUAQ-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of 10 kΩ for both R1 and R2. The device operates within a supply voltage range of -50 V and supports a maximum collector current of -100 mA. Electrical characteristics include a DC current gain (hFE) minimum of 30 at -5V/-5mA, an input leakage current of -0.88 mA at -5V, and a transition frequency (fT) of 250 MHz. Thermal performance specifies a power dissipation of 330 mW and a junction-to-ambient thermal resistance of 375 °C/W. The component is housed in an SOT-323 package and is qualified to AEC-Q101 standards.

Feature Summary

• Epitaxial planar die construction with integrated biasing resistors
• Qualified to AEC-Q101 automotive reliability standards
• Surface mount package designed for automated assembly
• Lead-free and fully RoHS compliant

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and compliance markings. The ADTA114EUAQ-7 designation corresponds to a 3,000-unit reel size. Confirm that the required automotive qualification and PPAP capabilities align with project specifications before finalizing procurement.

Selection Notes

Select this component when a PNP digital transistor with 10 kΩ base and emitter resistors is required in an SOT-323 package. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the thermal design accommodates the 330 mW power dissipation limit. Verify compatibility with automated assembly processes due to the surface mount form factor.

Part Context

This part belongs to the ADTA114 series of pre-biased transistors from Diodes Incorporated. The 'U' indicates the SOT-323 case style, while 'AQ' denotes AEC-Q101 automotive qualification. The '-7' suffix specifically identifies the tape and reel packaging configuration containing 3,000 units per reel.

Replacement Considerations

Cross-reference with other ADTA114 variants such as ADTA114ECAQ-7 or DDTA114EUA-7-F only if package dimensions and electrical parameters match exactly. Verify resistor tolerances and hFE ranges to ensure functional equivalence in the target circuit.
