NHDTC143ZTR

Overview

The NHDTC143ZTR is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a SOT23 (TO-236AB) surface-mount package. It integrates bias resistors R1 and R2 with typical values of 4.7 kΩ and 47 kΩ, respectively. The device supports a collector-emitter voltage (VCEO) of 80 V and a continuous output current (IO) of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at IC = 10 mA, a transition frequency (fT) of 170 MHz, and a total power dissipation (Ptot) of 250 mW at Tamb ≤ 25 °C. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Built-in bias resistors simplify circuit design by eliminating the need for external input components.
• High breakdown voltage capability suitable for demanding digital switching applications.
• AEC-Q101 qualified for automotive electronics reliability standards.

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 size or tape width. Confirm RoHS compliance status and lead times directly with authorized distributors prior to procurement. Ensure the component matches the required automotive qualification level if intended for vehicle systems.

Selection Notes

Select this component when a compact NPN solution with integrated base biasing is required. The 4.7 kΩ input resistor value provides a specific drive characteristic distinct from other series variants like the NHDTC123JT. Verify that the 80 V rating meets the system voltage requirements and that the SOT23 package footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the NHDTC123JT/143ZT/114YT series of NPN resistor-equipped transistors. It serves as the NPN complement to the NHDTA143ZT PNP RET. The 'Z' marking code distinguishes it within the SOT23 package family, differentiating it from other resistance ratios in the same series.

Replacement Considerations

Direct functional substitutes within the same series include NHDTC123JT and NHDTC114YT, provided their respective resistor values (R1/R2) match the circuit design requirements. Cross-manufacturer equivalents should be verified for pinout compatibility and electrical parameter alignment.
