NHDTA114EU-QX

Overview

The NHDTA114EU-QX is a PNP Resistor-Equipped Transistor (RET) manufactured by Nexperia, designed for surface-mount applications in the SC-70 (SOT-323) package. It integrates a single PNP bipolar junction transistor with internal biasing resistors to simplify circuit design and reduce board space. The device features a maximum collector-emitter voltage of 80 V and a continuous collector current of 100 mA. Key electrical parameters include a DC current gain (hFE) minimum of 100, a transition frequency (fT) of 150 MHz, and a power dissipation rating of 315 mW. It operates within a temperature range of -55°C to +150°C and includes an integrated base resistor (R1) of 10 kOhms and emitter resistor (R2) of 10 kOhms.

Procurement Notes

Verify the specific suffix 'QX' against the manufacturer's official datasheet to confirm packaging details and automotive compliance status. Ensure that the ordering information matches the exact part number required for your bill of materials, as suffix variations may indicate different reel sizes or tape specifications without altering the core electrical function.

Selection Notes

Select this component when a compact PNP switching solution with built-in biasing is required for automotive or industrial environments. Compare the 80 V breakdown voltage and 100 mA current rating against circuit requirements. Consider the SOT-323 package constraints for thermal management and spatial limitations relative to alternative discrete transistor configurations.

Part Context

This part belongs to the NHDTA series of NPN/PNP Resistor-Equipped Transistors from Nexperia. The 'Q' designation typically indicates automotive qualification, aligning with AEC-Q101 standards. It serves as a pre-biased alternative to discrete BJT and resistor combinations, offering improved consistency and reduced assembly complexity in high-volume manufacturing processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching the PNP polarity, 80 V voltage rating, and SOT-323 package dimensions before considering alternative RETs from other manufacturers.
