NHDTC143ZUF

Overview

The NHDTC143ZUF is an NPN Resistor-Equipped Transistor (RET) from the Nexperia NHDTC123JU/143ZU/114YU series, housed in a SOT323 (SC-70) surface-mounted package. It features a collector-emitter voltage (VCEO) of 80 V and an output current capability of 100 mA. The device integrates bias resistors with typical values of R1 = 4.7 kΩ and R2 = 47 kΩ, resulting in a resistor ratio of 10. Key electrical characteristics include a DC current gain (hFE) minimum of 100 at IC = 10 mA, a transition frequency (fT) of 170 MHz, and a total power dissipation of 235 mW at Tamb ≤ 25 °C. The operating temperature range spans 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 suitable for digital switching applications.
• Offers 100 mA output current capability within a compact SOT323 package.

Applications

• Digital logic applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape configuration. Ensure the part number matches the exact resistance values and package type required for the design. Cross-reference the marking code '5R' with manufacturing site codes to validate authenticity and traceability during the procurement process.

Selection Notes

Select this component when a compact NPN transistor with integrated base and pull-down resistors is required for space-constrained designs. The 4.7 kΩ input resistor value determines the drive current requirements compared to discrete alternatives. Consider the thermal resistance characteristics and derating curves if the application involves significant power dissipation or elevated ambient temperatures.

Part Context

This device belongs to the NHDTC123JU/143ZU/114YU series of NPN Resistor-Equipped Transistors. It shares the same SOT323 package and general electrical specifications as the NHDTC123JU and NHDTC114YU variants, differing primarily in the internal bias resistor values. The PNP complement for this series is the NHDTA143ZU.

Replacement Considerations

The direct PNP complement is NHDTA143ZU. Other RETs in the same series include NHDTC123JU and NHDTC114YU, which share the package but have different resistor ratios.
