NHDTA114YUX

Overview

The NHDTA114YUX is a PNP Resistor-Equipped Transistor (RET) from the Nexperia NHDTA123JU/143ZU/114YU series, housed in an SOT323 (SC-70) surface-mounted package. It features a collector-emitter voltage (VCEO) of -80 V and an output current capability of -100 mA. The device integrates bias resistors with typical values of R1 = 10 kΩ and R2 = 47 kΩ, resulting in a resistor ratio of 4.7. Key electrical characteristics include a DC current gain (hFE) minimum of 100 at -10 mA, a transition frequency (fT) of 150 MHz, and a total power dissipation of 235 mW at 25 °C on a single-sided FR4 PCB. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Provides high breakdown voltage and 100 mA output current capability for robust switching.
• Reduces pick and place costs through compact SOT323 packaging.

Applications

• Digital applications
• Cost saving alternative for BC856 series in digital applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging format and manufacturing site codes. Ensure the procurement channel sources products directly from authorized distributors or Nexperia to guarantee authenticity and traceability. Confirm that the delivered components match the NHDTA114YU part number specifications before integration into production lines.

Selection Notes

Select this component when a PNP transistor with integrated base biasing is required for space-constrained designs. The 10 kΩ input resistor value suits applications needing moderate drive currents. Verify that the -80 V collector-emitter voltage rating exceeds the maximum circuit voltage. Consider the SOT323 footprint compatibility during PCB layout planning to ensure proper soldering and thermal performance.

Part Context

The NHDTA114YUX belongs to the NHDTA123JU/143ZU/114YU series of PNP resistor-equipped transistors. This series shares the same SOT323 package and general electrical characteristics but differs in internal bias resistor values. The 'Y' designation specifically indicates the 10 kΩ / 47 kΩ resistor configuration within this family.

Replacement Considerations

Direct substitutes within the same series include NHDTA123JU and NHDTA143ZU, though their bias resistor values differ. For NPN equivalents, consider the NHDTC114YU series. Verify pinout compatibility and resistor ratios when replacing with other RET families.
