NHDTA144EUF

Overview

The NHDTA144EUF 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 and R2, both specified at 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 and VCE = -5 V, and a transition frequency (fT) typical value of 150 MHz. Total power dissipation is rated at 235 mW in free air.

Feature Summary

• Integrates PNP transistor with dual 47 kΩ bias resistors to simplify circuit design
• Provides high breakdown voltage capability for robust switching applications
• Reduces component count and pick-and-place costs through single-package integration

Applications

• Digital logic interface circuits
• Controlling integrated circuit inputs
• Switching loads in general-purpose electronics

Procurement Notes

Verify the specific suffix 'F' against the manufacturer's latest ordering information to confirm tape-and-reel packaging specifications. Confirm that the non-automotive qualification status aligns with your application requirements, as automotive-grade alternatives are available separately. Always consult the most recent product data sheet before finalizing design implementations.

Selection Notes

Select this component when a compact PNP switching solution with fixed base biasing is required. The 47 kΩ resistor values are suitable for standard digital logic levels. Ensure the operating temperature range fits within the specified -55 °C to 150 °C ambient limits. Consider the SOT323 thermal resistance if high duty cycle operation is expected.

Part Context

This part belongs to the NHDTA114/124/144EU series of PNP resistor-equipped transistors. It serves as the PNP counterpart to the NHDTC144EU NPN RET. The series offers a cost-effective alternative to discrete transistor-resistor networks in space-constrained designs requiring simplified biasing configurations.

Replacement Considerations

Direct pin-compatible substitutes within the same series include NHDTA114EU and NHDTA124EU, differing only in internal resistor values. For NPN polarity replacement, consider the NHDTC144EU. Verify that any substitute maintains the required -80 V breakdown voltage and -100 mA current rating.
