NHDTA124ET-QR

Overview

The NHDTA124ET-QR is a PNP digital transistor from Nexperia, housed in an SOT-23 (TO-236AB) surface-mount package. It integrates a single PNP bipolar junction transistor with internal biasing resistors on one monolithic chip. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 80 V and an emitter-base voltage (VEBO) of 10 V. The device supports a continuous collector current of 100 mA and dissipates up to 250 mW of power. It operates within a temperature range of -55°C to +150°C and is qualified to the AEC-Q101 standard for automotive reliability.

Feature Summary

• Integrated PNP transistor with built-in biasing resistors reduces component count and board space
• Automotive-grade qualification ensures high reliability under demanding environmental conditions
• High thermal stability allows operation at elevated temperatures up to 150°C

Applications

• Automotive logic switching and level shifting circuits
• General-purpose digital buffering and inversion
• Load switching in vehicle body control modules

Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's official datasheet to confirm reel packaging details and tape-and-reel dimensions. Ensure the part number matches the exact AEC-Q101 qualification grade required for your design. Cross-reference the ordering code with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a PNP digital switch with an 80 V collector-emitter rating is required. The integrated resistor configuration simplifies drive circuit design compared to discrete BJTs. Verify that the 100 mA current capability meets the load requirements. Consider the SOT-23 footprint constraints during PCB layout to ensure adequate thermal dissipation for the 250 mW power rating.

Part Context

This part belongs to Nexperia's portfolio of pre-biased transistors designed to replace multiple discrete components. The NHDTA series specifically features PNP configurations with various resistor values. The '-Q' designation indicates automotive qualification, while '-ET' specifies the SOT-23 package type. This family targets applications requiring compact, reliable switching solutions in constrained spaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult Nexperia's official replacement guide or contact technical support directly for validated cross-references. Do not assume functional equivalence with other PNP digital transistors without verifying pinout compatibility and electrical parameter margins.
