NHDTA114YU-QX

Overview

The NHDTA114YU-QX is a PNP digital transistor manufactured by Nexperia, housed in an SC-70-3 (SOT323) surface-mount package. It integrates a single PNP bipolar junction transistor with internal biasing resistors on a silicon substrate. Key electrical parameters include a collector-emitter voltage of 80 V, a collector-base voltage of 80 V, and an emitter-base voltage of 7 V. The device features a DC current gain (hFE) minimum of 100 and a transition frequency of 150 MHz. Power dissipation is rated at 315 mW, with a collector-emitter saturation voltage of 100 mV. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Integrated biasing network reduces external component count
• High thermal stability suitable for demanding environments
• Compact SMD footprint for space-constrained designs

Applications

• Automotive systems requiring AEC-Q101 compliance
• General-purpose switching applications
• Logic level translation circuits

Procurement Notes

Verify the specific suffix 'QX' against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure the order matches the exact part number NHDTA114YU-QX to avoid confusion with similar variants. Confirm RoHS compliance status through the supplier's declaration documents prior to procurement.

Selection Notes

Select this component when a compact PNP digital transistor with integrated resistors is required for automotive or industrial applications. The 80 V rating and high operating temperature limit make it suitable for harsh environments. Verify that the SC-70-3 package dimensions fit the PCB layout constraints and that the 315 mW power dissipation meets the thermal requirements of the design.

Part Context

This part belongs to Nexperia's portfolio of digital transistors designed for simplified circuit design. The 'NH' prefix typically denotes a NPN/PNP combination or specific digital transistor series, while the 'Q' suffix indicates automotive qualification. The SC-70-3 package provides a small outline for high-density mounting.

Replacement Considerations

Check for direct substitutes within the Nexperia NHDA/NHDB series or equivalent parts from other manufacturers offering identical pinouts and electrical characteristics in the SOT323 package. Ensure any replacement maintains the same voltage ratings and integration features.
