NHDTC144EUX

Overview

The NHDTC144EUX 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 with a typical value of 47 kΩ and a ratio of 1. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V, a continuous output current (IO) of 100 mA, and a DC current gain (hFE) minimum of 100 at IC = 10 mA. The device operates within a junction temperature range of -55 °C to +150 °C and has a total power dissipation of 235 mW.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• Provides high breakdown voltage capability for robust switching applications
• Reduces pick and place costs through compact single-package integration

Applications

• Digital logic interface circuits
• Controlling integrated circuit inputs
• Switching loads in general-purpose digital applications

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official ordering information to confirm packaging details such as reel size or tape width. Ensure the procurement source provides the correct JEITA type number matching the datasheet specifications. Confirm RoHS compliance status directly from the supplier documentation prior to finalizing orders.

Selection Notes

Select this component when a single NPN transistor with integrated base biasing is required to save board space. The 47 kΩ internal resistor value determines the input drive requirements; verify that the driving source can supply sufficient current to activate the transistor effectively. Consider the 80 V rating for appropriate voltage headroom in the target application circuit.

Part Context

This part belongs to the NHDTC114/124/144EU family of NPN resistor-equipped transistors. The '144' designation specifically indicates the 47 kΩ resistor configuration, distinguishing it from the 10 kΩ (NHDTC114EU) and 22 kΩ (NHDTC124EU) variants within the same SOT323 package footprint.
