ADTA114ECAQ-7

Overview

The ADTA114ECAQ-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction with built-in biasing resistors where R1 equals R2, both nominally 10 kOhms. The device operates with a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. It has a power dissipation rating of 310 mW and a transition frequency of 250 MHz. The component is housed in an SOT-23 package and is qualified to AEC-Q101 standards for high reliability.

Feature Summary

• Integrated biasing network with equal internal resistors simplifies circuit design
• Qualified to AEC-Q101 automotive standards for high reliability applications
• Totally lead-free and fully RoHS compliant construction
• Halogen and antimony free green device formulation

Applications

• Automotive electronic circuits requiring AEC-Q101 qualification
• General purpose switching applications utilizing pre-biased configuration
• Surface mount assembly processes compatible with SOT-23 packaging

Procurement Notes

Verify the specific ordering suffix when purchasing. The -7 suffix indicates a reel quantity of 3,000 units on an 8 mm tape width. Confirm that the required automotive compliance and PPAP capabilities align with project specifications before procurement. Ensure the SOT-23 package dimensions match the target PCB layout constraints.

Selection Notes

Select this component when a PNP pre-biased transistor with integrated 10 kOhm resistors is required. The AEC-Q101 qualification makes it suitable for automotive environments. Consider the -50 V supply voltage limit and -100 mA output current capability during circuit design. Verify thermal management requirements against the 310 mW power dissipation rating at ambient temperature.

Part Context

This part belongs to the ADTA series of PNP pre-biased transistors from Diodes Incorporated. The ECAQ designation specifies the SOT-23 package variant with automotive grade qualification. The -7 suffix denotes the standard 3,000-unit reel packaging format used for automated surface mount assembly lines.

Replacement Considerations

Cross-reference with other Diodes Incorporated ADTA series parts sharing the same electrical characteristics and SOT-23 package. Verify resistor values and polarity compatibility before substitution. Check if alternative suppliers offer equivalent AEC-Q101 qualified PNP pre-biased transistors with matching pinouts.
