NHDTC123JU-QX

Overview

The NHDTC123JU-QX is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a compact SOT-323 (SC-70) surface-mount package. It integrates a single NPN bipolar junction transistor with built-in biasing resistors: R1 at 2.2 kΩ and R2 at 47 kΩ. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 80 V, a continuous collector current (Ic) of 100 mA, and a power dissipation (Pd) of 315 mW. The device features a DC current gain (hFE) minimum of 100 at 10 mA and 5 V, with a transition frequency (fT) of 170 MHz. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 qualification for automotive applications.

Feature Summary

• Integrates NPN BJT with fixed base and emitter resistors to simplify circuit design and reduce component count.
• AEC-Q101 qualified for automotive reliability standards.
• High breakdown voltage capability suitable for digital switching applications.

Applications

• Digital logic level shifting and interface circuits
• Controlling IC inputs in embedded systems
• Switching small loads in automotive electronics

Procurement Notes

Verify the specific suffix 'QX' against the manufacturer's official datasheet to confirm packaging details and any distinct material composition changes compared to standard variants. Ensure the ordering part number matches the required AEC-Q101 automotive grade specification. Cross-reference the internal manufacturer code 934668972115 for accurate identification during sourcing.

Selection Notes

Select this component when a compact NPN switch with integrated biasing is required for space-constrained designs. The 80 V rating and 100 mA current capacity make it suitable for general-purpose digital switching. Verify that the 2.2 kΩ base resistor value aligns with the driving source impedance and desired switching speed requirements for the target application.

Part Context

This part belongs to the NHDTC123 series of Resistor-Equipped Transistors (RETs). It serves as the NPN counterpart to the NHDTA123JU PNP variant. The series is designed to replace discrete resistor-transistor combinations, offering cost savings in pick-and-place manufacturing while maintaining high performance in small SMD packages like SOT-323.

Replacement Considerations

Direct functional substitutes within the same RET family include the NHDTC123JUX. For pin-compatible alternatives with similar electrical characteristics, consider other NPN RETs with comparable VCEO and Ic ratings, ensuring resistor values match the design requirements.
