NHDTA124EU-QX

Overview

The NHDTA124EU-QX is a PNP digital transistor manufactured by Nexperia, housed in an SOT-323 (SC-70) surface-mount package. It integrates a single PNP bipolar junction transistor with an internal base resistor to simplify circuit design and reduce board space. The device features a collector-emitter voltage rating of 80 V and an emitter-base voltage rating of 10 V. It supports a continuous collector current of 100 mA and dissipates up to 235 mW of power. The component operates within a temperature range of -55 °C to +150 °C and meets automotive qualification standards.

Feature Summary

• Integrated base resistor eliminates external biasing components
• Automotive qualified for high reliability applications
• Compact SOT-323 footprint for space-constrained designs

Applications

• Load switching in automotive electronics
• Logic level translation circuits
• General purpose switching in industrial control systems

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the part number matches the exact automotive grade requirements for your target application before finalizing orders.

Selection Notes

Select this component when a compact PNP switch with integrated biasing is required. Compare the 80 V rating and 100 mA current capacity against load requirements. Consider the SOT-323 thermal performance for your specific power dissipation needs.

Part Context

This part belongs to Nexperia's NHDTC/NHDTA series of digital transistors. These devices combine a single transistor with one or two resistors on a monolithic chip. The 'NHDTA' prefix typically denotes a PNP configuration with a single base resistor, designed to replace multiple discrete components.

Replacement Considerations

Direct substitutes include other PNP digital transistors in SC-70 packages with similar 80V ratings, such as the NHDTC124EUX from the same manufacturer family.
