NHDTC123JUX

Overview

The NHDTC123JUX is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a SOT-323 (SC-70) surface-mount package. It features a collector-emitter voltage of 80 V and an output current capability of 100 mA. The device integrates a base resistor (R1) with a typical value of 2.2 kΩ and an emitter resistor (R2) of 47 kΩ, resulting in a bias resistor ratio of 21. Key electrical characteristics include a DC current gain (hFE) minimum of 100 at 10 mA, a transition frequency of 170 MHz, and a total power dissipation of 235 mW. The component operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Provides high breakdown voltage for robust performance in digital switching applications.
• Offers 100 mA output current capability suitable for controlling IC inputs and switching loads.

Applications

• Digital logic interface circuits
• Controlling integrated circuit inputs
• Switching small loads

Procurement Notes

Verify the specific ordering suffix 'U' corresponds to the SOT-323 package variant when sourcing. Confirm RoHS compliance status through official distributor channels or manufacturer documentation prior to procurement. Ensure the supply chain provides valid traceability data consistent with Nexperia's quality standards for this discrete semiconductor component.

Selection Notes

Select the NHDTC123JUX when a compact NPN solution with integrated biasing is required for space-constrained designs. The 2.2 kΩ input resistance is optimal for standard logic level driving. Consider the SOT-323 footprint constraints during PCB layout. Verify that the 80 V rating meets the maximum voltage requirements of the target application environment.

Part Context

This component belongs to the NHDTC123JU/143ZU/114YU series of NPN resistor-equipped transistors. It serves as the NPN counterpart to the NHDTA123JU PNP RET. The 'JUX' designation specifically identifies the 2.2 kΩ / 47 kΩ resistor configuration within the SOT-323 package family offered by Nexperia.

Replacement Considerations

Direct functional substitutes within the same series include NHDTC143ZU and NHDTC114YU, which share the SOT-323 package but differ in internal resistor values. For pin-compatible alternatives in different packages, consider the SOT-23 variant NHDTC123JT/SOT23.
