NHDTA144EUX

Overview

The NHDTA144EUX is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an SOT323 (SC-70) surface-mount package. It integrates a PNP transistor with built-in bias resistors: R1 is 47 kΩ and R2 is 47 kΩ. 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 DC current gain (hFE) minimum of 100 at IC = -10 mA, a transition frequency (fT) typical value of 150 MHz, and a collector-emitter saturation voltage (VCEsat) maximum of -100 mV. Total power dissipation reaches 235 mW at Tamb ≤ 25 °C on a single-sided FR4 PCB.

Feature Summary

• Integrates a PNP transistor with two internal bias resistors to simplify circuit design and reduce component count.
• Provides high breakdown voltage capability suitable for general-purpose switching applications.
• Delivers 100 mA output current capability within a compact SOT323 surface-mount package.

Applications

• Digital logic interface circuits
• Controlling integrated circuit 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 that the non-automotive qualified status aligns with the target application requirements, as automotive-grade alternatives are available separately. Ensure compatibility with standard SMT pick-and-place processes for the SC-70 footprint.

Selection Notes

Select this component when a PNP configuration with a 47 kΩ base resistor is required for digital switching. Compare the 47 kΩ internal resistance against other series variants like NHDTA114EU (10 kΩ) or NHDTA124EU (22 kΩ) based on specific drive current needs. Verify that the -80 V rating meets the system's voltage constraints and that the SOT323 package fits the board layout.

Part Context

This part belongs to the Nexperia NHDTA114/124/144EU series of PNP resistor-equipped transistors. It serves as the PNP complement to the NHDTC144EU NPN RET. The series shares the same SOT323 package and general features but differs in internal resistor values and complementary pairing.

Replacement Considerations

NHDTC144EU is the documented NPN complement within the same series. For direct functional replacement in PNP roles, verify equivalent resistor values and voltage ratings against other manufacturers' RET offerings.
