NHDTC143ZUX

Overview

The NHDTC143ZUX is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a SOT323 (SC-70) surface-mount package. It features a collector-emitter voltage (VCEO) of 80 V and a continuous output current (IO) of 100 mA. The device integrates bias resistors with typical values of R1 = 4.7 kΩ and R2 = 47 kΩ, yielding 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 on single-sided copper PCBs. Operating temperatures range 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 capability for robust switching applications.
• Offers 100 mA output current capability suitable for controlling IC inputs and switching loads.

Applications

• Digital applications
• Controlling IC inputs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Ensure the part number matches the exact series requirements for your design. Cross-reference the marking code '5R' to validate authenticity upon receipt. Confirm that the non-automotive qualification status aligns with your application constraints before finalizing procurement.

Selection Notes

Select this component when a compact NPN switch with integrated base biasing is required. The SOT323 package offers space efficiency for dense layouts. Consider the 80 V rating and 100 mA current limit to ensure adequate headroom for the intended load. Verify thermal management needs based on the specified power dissipation limits under expected ambient conditions.

Part Context

This device belongs to the NHDTC123JU/143ZU/114YU series of NPN resistor-equipped transistors. It serves as the complement to the PNP NHDTA143ZU within the same family. All variants share the SOT323 package and similar electrical profiles, differing primarily in the internal resistor values to accommodate various logic drive requirements.

Replacement Considerations

Direct functional substitutes within the same series include NHDTC123JU and NHDTC114YU, which differ only in internal resistance values. For pin-compatible alternatives with different ratings, consult the broader Nexperia RET portfolio. Ensure any replacement maintains the SOT323 footprint and meets the 80 V / 100 mA specifications.
