ADTA114ECAQ-13

Overview

The ADTA114ECAQ-13 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 kΩ. The device operates with a maximum supply 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. Qualified to AEC-Q101 standards for high reliability, it functions within a temperature range of -55°C to +150°C and is housed in an SOT-23 package.

Feature Summary

• Integrated biasing network with equal nominal resistance values for simplified circuit design
• Automotive-grade qualification ensuring high reliability under demanding conditions
• Lead-free and halogen-free green device compliant with environmental directives

Applications

• Automotive electronic systems requiring qualified discrete components
• General-purpose switching applications utilizing integrated biasing
• Surface mount assembly processes compatible with standard SOT-23 footprints

Procurement Notes

Verify the specific ordering suffix '-13' against official documentation to confirm the 10,000-unit reel quantity. Confirm that the '2C0' marking code aligns with the required production date codes for your manufacturing timeline. Ensure compliance requirements match the specified RoHS and PPAP capabilities listed in the datasheet.

Selection Notes

Select this component when an automotive-qualified PNP digital transistor is required with a 10 kΩ base resistor configuration. The SOT-23 package suits space-constrained designs needing a single-channel pre-biased solution. Verify that the -50 V collector-emitter voltage and -100 mA current ratings meet the specific load requirements of the target application circuit.

Part Context

This part belongs to the ADTA114 series of PNP pre-biased transistors from Diodes Incorporated. The 'Q' designation indicates automotive qualification, while the '-13' suffix specifies the tape and reel packaging format containing 10,000 units per reel. It shares electrical characteristics with other variants in the family but differs in packaging and compliance certifications.

Replacement Considerations

Check for equivalent parts within the same manufacturer's portfolio that share the SOT-23 footprint and identical 10 kΩ internal resistor ratios. Verify that any substitute maintains AEC-Q101 qualification if automotive use is intended. Confirm pinout compatibility and thermal resistance values before implementation.
