NHDTA143ZU-QX

Overview

The NHDTA143ZU-QX is a PNP resistor-equipped transistor (RET) from Nexperia, housed in an SOT323 (SC-70) surface-mount package. It integrates a single PNP bipolar junction transistor with built-in biasing resistors: R1 is 4.7 kΩ and R2 is 47 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of 80 V and a collector-base voltage (VCBO) of 80 V, with an emitter-base voltage (VEBO) rating of 7 V. Key electrical parameters include a minimum DC current gain (hFE) of 100, a saturation voltage of 100 mV, and a power dissipation capability of 315 mW. The transition frequency (fT) is 150 MHz, and it operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates PNP transistor with two internal resistors to simplify circuit design and reduce component count.
• High breakdown voltage capability suitable for demanding digital switching applications.
• Compact SOT323 (SC-70) plastic surface-mount package optimized for automated pick-and-place assembly.

Applications

• Digital logic interface circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix '-QX' against the official Nexperia datasheet to confirm packaging details and any automotive or qualification markings. Ensure the ordering part number matches the required reel or cut-tape configuration. Cross-reference the manufacturer's latest documentation for any updates on lead times or lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when a compact PNP solution with integrated base and pull-down resistors is required. The 4.7 kΩ input resistor value determines the base drive current requirements. Verify that the 80 V voltage rating exceeds the maximum circuit voltage. Consider the 315 mW power dissipation limit in the SC-70 package for thermal management in high-density designs.

Part Context

This part belongs to the NHDTA series of PNP resistor-equipped transistors. It serves as a complement to the NHDTC143ZU NPN RET. The 'Q' suffix typically indicates AEC-Q101 automotive qualification, while 'X' denotes the tape and reel packaging format. It is designed as a cost-saving alternative to discrete BJT combinations in digital applications.

Replacement Considerations

Direct functional substitutes include the NHDTC143ZU for NPN applications or other NHDTA series variants with different resistor values. Verify pinout compatibility and electrical ratings before substitution. Check if the replacement part holds the same automotive qualification status if required by the design.
