NHDTA124EUX

Overview

The NHDTA124EUX is a PNP Resistor-Equipped Transistor (RET) from the Nexperia EU series, housed in an SOT323 (SC-70) surface-mount package. It integrates two bias resistors with typical values of 22 kΩ each and a ratio of 1. The device supports a collector-emitter voltage of -80 V and a continuous output current of -100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 70 at -10 mA, a transition frequency of 150 MHz, and a total power dissipation of 235 mW at 25 °C on single-sided copper PCBs. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Integrates built-in 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 SMD packaging.

Applications

• Digital logic applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify that the specific suffix 'U' corresponds to the standard SOT323 reel configuration as defined in the official ordering information table. Confirm the product status is listed as 'Production' rather than development or qualification stages before finalizing procurement plans.

Selection Notes

Select this component when a PNP RET with 22 kΩ internal biasing is required in a small footprint. Ensure the application voltage does not exceed the -80 V collector-emitter rating and that the thermal environment allows for the specified 235 mW power dissipation on the target PCB layout.

Part Context

This part belongs to the NHDTA114/124/144EU series of PNP resistor-equipped transistors. It serves as the digital complement to the NHDTC124EU NPN variant. Unlike automotive-qualified versions, this specific EU series revision is designated for non-automotive general-purpose applications.

Replacement Considerations

Direct functional substitutes within the same family include NHDTA114EU and NHDTA144EU, which share the SOT323 package but differ in internal resistor values. For equivalent performance in different packages, consider the NHDTA124ETR in SOT23.

FAQ

Is the NHDTA124EUX qualified for automotive use?

No, the EU series data sheet explicitly states that these products are not automotive qualified and are intended for non-automotive applications.

What is the pin configuration for the SOT323 package?

Pin 1 is the Input (Base), Pin 2 is GND (Emitter), and Pin 3 is Output (Collector).

What is the typical value of the integrated bias resistors?

For the NHDTA124EU type, both R1 and R2 have a typical resistance value of 22 kΩ.
