NHDTA123JUX

Overview

The Nexperia NHDTA123JUX is a PNP Resistor-Equipped Transistor (RET) housed in an SOT-323 (SC-70) surface-mount package. It integrates a single PNP transistor with built-in bias resistors: R1 is typically 2.2 kΩ and R2 is typically 47 kΩ, yielding a typical resistor ratio of 21. The device supports a collector-emitter voltage (VCEO) of -80 V and a continuous output current (IO) of -100 mA. 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 (Ptot) of 235 mW at 25 °C ambient temperature.

Feature Summary

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

Applications

• Digital applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Confirm that the non-automotive qualified status aligns with the target application requirements, as automotive-grade alternatives may be necessary for regulated environments.

Selection Notes

Select this component when a compact PNP solution with integrated base and emitter resistors is required. Ensure the 2.2 kΩ input resistance matches the driving source impedance. Verify that the -80 V collector-emitter voltage rating exceeds the maximum circuit voltage to prevent breakdown during operation.

Part Context

This part belongs to the NHDTA123JU/143ZU/114YU series of PNP Resistor-Equipped Transistors. It serves as the PNP counterpart to the NHDTC123JU NPN RET. All variants in this series share the same SOT-323 package and pinout but differ in internal resistor values to accommodate various logic drive levels.

Replacement Considerations

NHDTC123JU is the NPN complement within the same series. For direct functional replacement, verify if the circuit topology requires PNP polarity. No other specific PNP substitutes are listed in the provided datasheet.
