NHDTC144EUF

Overview

The NHDTC144EUF is an NPN Resistor-Equipped Transistor (RET) from the Nexperia EU series, housed in a SOT323 (SC-70) surface-mount package. It integrates a single NPN transistor with built-in bias resistors R1 and R2, both typically 47 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V, a continuous output current (IO) of 100 mA, and a total power dissipation (Ptot) of 235 mW at 25 °C on a single-sided FR4 PCB. The device features a minimum DC current gain (hFE) of 100 and a transition frequency (fT) of 170 MHz.

Feature Summary

• Integrates NPN transistor with dual 47 kΩ bias resistors to simplify circuit design
• Provides high breakdown voltage capability for robust switching applications
• Reduces component count and board space requirements compared to discrete solutions

Applications

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

Procurement Notes

Verify the specific suffix 'F' against official Nexperia documentation to confirm packaging details, as standard datasheets often list 'EU' variants. Confirm RoHS compliance status and automotive qualification level, noting that recent revisions may distinguish between qualified and non-qualified versions within the same series. Ensure ordering codes match the required reel or cut-tape quantities.

Selection Notes

Select this component when an 80 V rating and 100 mA current capacity are required in a compact SOT323 footprint. The 47 kΩ internal resistor ratio suits standard digital logic levels. Compare against the BC846 series if cost reduction is a priority. Verify thermal derating requirements for high ambient temperatures or multi-layer PCB mounting conditions.

Part Context

This part belongs to the NHDTC114/124/144EU family, differentiated by internal resistor values (10 kΩ, 22 kΩ, and 47 kΩ respectively). All share the same SOT323 package and general electrical characteristics. The PNP complement for this series is the NHDTA144EU. These devices replace discrete transistor-resistor networks to save space.

Replacement Considerations

Direct substitutes include other NPN RETs with 80 V VCEO, 100 mA IO, and ~47 kΩ internal resistors in SOT323 packages. Check pinout compatibility and exact resistor tolerances. Alternative manufacturers offer similar BRT devices, but verify saturation voltage and hFE curves match application needs.
