NHDTC114YU-QX

Overview

The NHDTC114YU-QX is a pre-biased NPN digital transistor manufactured by Nexperia, housed in an SC-70 (SOT-323) surface-mount package. It integrates internal base resistor R1 of 10 kOhms and emitter resistor R2 of 47 kOhms to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 80 V, a continuous collector current (Ic) of 100 mA, and a power dissipation (Pd) of 235 mW. The device features a minimum DC current gain (hFE) of 100 at 10 mA and 5 V, with a transition frequency (fT) of 170 MHz. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Integrated biasing resistors reduce component count and board space requirements
• Automotive-grade reliability certified under AEC-Q101 standards
• High switching speed with 170 MHz transition frequency for efficient signal processing

Applications

• Automotive electronic control units requiring robust switching components
• General-purpose logic level translation and buffering in consumer electronics
• Driver circuits for low-power loads in industrial control systems

Procurement Notes

Verify the specific suffix 'QX' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure that the ordering information matches the exact part number required for your bill of materials, as suffixes may indicate variations in reel size or tape specifications provided by authorized distributors.

Selection Notes

Select this component when an NPN configuration with integrated biasing is required for space-constrained designs. The 80 V rating and 100 mA current capacity make it suitable for moderate load applications. Consider the SOT-323 package dimensions for PCB layout constraints and verify thermal management needs given the 235 mW power dissipation limit in enclosed environments.

Part Context

This part belongs to the NHDTC114 series of Resistor-Equipped Transistors (RETs). It shares functional characteristics with other members of the family but differs in polarity and specific resistor values. The 'Q' designation indicates automotive grade qualification, distinguishing it from standard commercial variants within the same product line.

Replacement Considerations

Direct substitutes include NHDTC114YUX and NHDTA114YU-QX, though polarity differences exist between NPN and PNP types. Verify pin compatibility and electrical ratings before substitution. Alternative RETs from the same series should be evaluated for matching resistor ratios and voltage thresholds.
