NHDTA124EUF

Overview

The NHDTA124EUF is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an SOT323 (SC-70) surface-mount package. It features built-in bias resistors with typical values of 22 kΩ for both R1 and R2. Key electrical parameters include a collector-emitter voltage (VCEO) of -80 V, a continuous output current (IO) of -100 mA, and a DC current gain (hFE) minimum of 70 at -10 mA. The device operates within a temperature range of -55 °C to +150 °C, with a total power dissipation of 235 mW on single-sided FR4 PCBs.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count.
• Provides high breakdown voltage capability suitable for digital switching applications.
• Offers cost-saving advantages by replacing discrete transistor and resistor combinations.

Applications

• Digital logic interface circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix 'EU' corresponds to the SOT323 package and non-automotive qualification status as defined in the official datasheet. Confirm that the ordering information matches the required resistance values and pin configuration before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP solution with integrated base biasing is required. Ensure the application voltage does not exceed the -80 V collector-emitter rating and that the load current remains within the -100 mA limit. Verify thermal constraints against the specified power dissipation curves for the target PCB layout.

Part Context

This part belongs to the NHDTA114/124/144EU series of PNP resistor-equipped transistors. The '124' designation specifically indicates the 22 kΩ / 22 kΩ resistor ratio configuration within the SC-70 plastic surface-mounted package family.

Replacement Considerations

The NHDTC124EU serves as the direct NPN complement within the same series. For discrete replacements, verify that external resistor values match the internal 22 kΩ specifications and that the package footprint aligns with SOT323 dimensions.
