NHDTC124ETVL

Overview

The NHDTC124ETVL is an NPN Resistor-Equipped Transistor (RET) from the Nexperia NHDTC114/124/144ET series, housed in a SOT-23 surface-mounted 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 transition frequency (fT) of 170 MHz. The device operates within an ambient temperature range of -55 °C to +150 °C, with a total power dissipation of 250 mW at Tamb ≤ 25 °C.

Feature Summary

• Integrates two internal bias resistors to simplify circuit design and reduce component count.
• Provides high breakdown voltage capability suitable for digital switching applications.
• Offers cost-saving alternative characteristics compared to standard discrete transistor configurations.

Applications

• Digital logic circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify that the specific suffix 'VL' corresponds to the requested packaging configuration, as datasheet ordering tables list the base type number without suffixes. Confirm RoHS compliance status through official Nexperia channels or distributor documentation prior to finalizing procurement orders.

Selection Notes

Select this component when a single NPN transistor with integrated base and emitter resistors is required. Ensure the 22 kΩ resistor values align with the target drive current and input impedance requirements. Verify that the 80 V rating meets the maximum voltage stress conditions of the application circuit.

Part Context

This part belongs to the NHDTC114/124/144ET family of NPN resistor-equipped transistors. The NHDTC124ET variant specifically distinguishes itself by utilizing 22 kΩ bias resistors, whereas the NHDTC114ET uses 10 kΩ and the NHDTC144ET uses 47 kΩ. All variants share the same SOT-23 package and core transistor characteristics.

Replacement Considerations

Direct functional substitutes within the same series include NHDTC114ET and NHDTC144ET, provided their respective resistor values are acceptable. For PNP polarity requirements, consider the NHDTA124ET complement. Verify pinout compatibility and thermal performance before substitution.
