NHDTC144ETVL

Overview

The NHDTC144ETVL is an NPN Resistor-Equipped Transistor (RET) from the Nexperia NHDTC114/124/144ET series, housed in a SOT23 surface-mounted package. It features built-in bias resistors with R1 and R2 both at 47 kΩ. Key electrical parameters include a collector-emitter voltage of 80 V, continuous collector current of 100 mA, and total power dissipation of 250 mW. The device offers a DC current gain (hFE) minimum of 100 and a transition frequency of 170 MHz. Operating temperature ranges from -55 °C to +150 °C.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count
• Provides high breakdown voltage capability for robust switching applications
• Reduces pick and place costs through integrated resistor configuration

Applications

• Digital logic applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix 'VL' against official Nexperia documentation to confirm packaging details such as reel size or tape specifications. Confirm that the non-automotive qualified version aligns with project requirements, as automotive variants carry distinct qualification standards. Ensure compatibility with standard SOT23 footprints during procurement planning.

Selection Notes

Select this component when a cost-effective alternative to discrete transistor-resistor networks is required. The 47 kΩ resistor ratio suits general-purpose digital switching where moderate base drive is sufficient. Verify thermal constraints for high-duty cycle operations, as power dissipation limits apply strictly within the specified ambient temperature range.

Part Context

This part belongs to the NHDTC114/124/144ET series, which shares identical pinouts and core transistor characteristics but differs in internal resistor values. The NHDTC144ET variant specifically utilizes 47 kΩ resistors for both R1 and R2, distinguishing it from the 10 kΩ and 22 kΩ configurations of its siblings.

Replacement Considerations

Direct substitutes include other NPN RETs with matching 47 kΩ bias resistors and SOT23 packaging. Verify pinout compatibility and ensure replacement parts meet the same 80 V and 100 mA ratings.
