NHDTC114EUX

Overview

The NHDTC114EUX is an NPN Resistor-Equipped Transistor (RET) from the Nexperia NHDTC114/124/144EU series, housed in a SOT323 (SC-70) surface-mount package. It features built-in bias resistors R1 and R2, both rated at 10 kΩ. The device supports a collector-emitter voltage of 80 V and an output current capability of 100 mA. Key electrical characteristics include a DC current gain (hFE) of 50 to 100 at IC = 10 mA and VCE = 5 V, a transition frequency (fT) of 170 MHz, and a maximum power dissipation of 235 mW on a single-sided FR4 PCB. The component is designed for digital applications and cost-effective circuit integration.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count
• Provides high breakdown voltage suitable for demanding switching environments
• Delivers 100 mA output current capability within a compact SMD footprint

Applications

• Digital logic interface circuits
• Controlling integrated circuit inputs
• Switching loads in low-power systems

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, as standard availability may vary by distributor. Confirm the revision status against the latest Nexperia datasheet, noting that recent updates have adjusted automotive qualification claims for this EU series. Ensure compatibility with standard SOT323 footprints during procurement planning.

Selection Notes

Select the NHDTC114EUX when a balanced 1:1 resistor ratio (R1/R2) is required for input driving tasks. Compare its 80 V rating against lower-voltage alternatives if higher breakdown is needed. Consider the PNP complement NHDTA114EU for complementary push-pull configurations or differential signaling requirements in the same package family.

Part Context

This component belongs to the NHDTC114/124/144EU series, which shares the SOT323 package but varies internal resistor values. The NHDTC114 variant specifically uses 10 kΩ for both base and emitter resistors, distinguishing it from the 22 kΩ (NHDTC124) and 47 kΩ (NHDTC144) counterparts. This series serves as a direct replacement for older discrete transistor-resistor combinations in space-constrained designs.

Replacement Considerations

The official PNP complement is the NHDTA114EU. For legacy replacements, verify pinout compatibility with BC846 series equivalents, though internal resistor tolerances may differ.
