NHDTC143ZTVL

Overview

The NHDTC143ZTVL is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a SOT-23 (TO-236AB) surface-mount package. It integrates a transistor with built-in bias resistors: R1 is typically 4.7 kΩ and R2 is typically 47 kΩ, yielding a ratio of 10. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V, continuous collector current of 100 mA, and total power dissipation of 250 mW at 25 °C. The device features a minimum DC current gain (hFE) of 100 and a transition frequency of 170 MHz. Operating temperature ranges from -55 °C to +150 °C.

Feature Summary

• Integrates NPN transistor with fixed internal bias resistors to simplify circuit design.
• AEC-Q101 qualified for automotive applications.
• High breakdown voltage capability suitable for demanding digital switching tasks.

Applications

• Digital logic circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix 'TVL' against the manufacturer's official ordering information to confirm packaging details such as reel size or tape width. Ensure the component matches the required RoHS compliance status for your assembly process. Cross-reference the marking code 'QL' on the physical device to authenticate the part number and manufacturing origin before integration into production lines.

Selection Notes

Select this component when a compact NPN solution with integrated base and pull-down resistors is required. The 4.7 kΩ input resistor value dictates the drive current requirements compared to other series variants like the NHDTC123JT or NHDTC114YT. Consider the 80 V rating and 100 mA current limit to ensure adequate headroom for the intended load switching application.

Part Context

This part belongs to the NHDTC123JT/143ZT/114YT series of 80 V, 100 mA NPN resistor-equipped transistors. All members share the same SOT-23 package and general electrical characteristics, differing primarily in the values of the internal bias resistors R1 and R2. The NHDTC143ZT variant specifically utilizes a 4.7 kΩ / 47 kΩ resistor configuration.

Replacement Considerations

Direct functional substitutes within the same series include NHDTC123JT and NHDTC114YT, though their different internal resistor values require circuit re-evaluation. The PNP complement NHDTA143ZT serves as a logical alternative for high-side switching configurations requiring identical resistance ratios.
