NHDTC143ZT-QR

Overview

The NHDTC143ZT-QR is an NPN digital transistor manufactured by Nexperia, housed in a surface-mount SOT-23 package. It features a collector-emitter maximum voltage (VCEO) of 80 V and a collector-base voltage (VCBO) of 50 V. The device supports a continuous collector current of 100 mA with a power dissipation rating of 250 mW. Operating temperatures range from -55 °C to +150 °C, and the emitter-base voltage (VEBO) is rated at 10 V.

Feature Summary

• Integrated biasing resistors for simplified circuit design
• High thermal stability suitable for demanding environments
• Automotive-grade qualification ensuring reliability

Applications

• Switching applications in automotive electronics
• Driver circuits for loads requiring high voltage tolerance
• General-purpose digital switching in industrial control systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and AEC-Q101 certification status against current datasheets. Ensure packaging integrity matches specified reel or cut tape formats to prevent handling damage during assembly.

Selection Notes

Select this component when an NPN digital transistor requires an 80 V collector-emitter breakdown voltage. The SOT-23 package suits space-constrained designs. Verify that the 100 mA continuous current rating meets load requirements and that the -55 °C to +150 °C operating range aligns with environmental conditions.

Part Context

This part belongs to Nexperia’s NHDTC series of pre-biased transistors designed for automotive and industrial markets. The suffix 'QR' indicates specific packaging and ordering details within the SOT-23 family. It serves as a higher-voltage alternative to standard 50 V digital transistors like the PDTC143ZT.

Replacement Considerations

Direct substitutes include other 80 V NPN digital transistors in SOT-23 packages such as the NHDTC123JT-QR or NHDTC114YT-QR. Verify pin compatibility and electrical parameters before substitution.
