NHDTA123JU-QX

Overview

The NHDTA123JU-QX is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an SOT323 (SC-70) surface-mount package. It integrates a single NPN transistor with built-in resistors: R1 of 2.2 kΩ and R2 of 47 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of 80 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 100, a breakdown voltage (VEBO) of 7 V, and a power dissipation rating of 315 mW. It operates within a temperature range of -55 °C to +150 °C and features a gain-bandwidth product (fT) of 150 MHz.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Integrated biasing resistors simplify circuit design and reduce component count
• High breakdown voltage capability suitable for robust switching applications

Applications

• Digital logic interface circuits
• Controlling IC inputs
• Switching loads in automotive systems

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the AEC-Q101 qualification status aligns with project requirements by checking the latest datasheet revision. Confirm RoHS compliance details directly from the manufacturer's declaration before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP solution with integrated base resistance is required for space-constrained designs. The SOT323 package offers a small footprint compared to larger transistor packages. Consider the 80 V voltage rating and 100 mA current limit to ensure adequate headroom for the intended load switching or signal driving application.

Part Context

This part belongs to the NHDTA series of PNP resistor-equipped transistors designed for digital applications. It serves as a cost-effective alternative to discrete resistor-transistor networks. The QX suffix typically denotes a specific packaging variant, often related to tape and reel quantities for automated assembly processes.

Replacement Considerations

The NHDTC123JU is the NPN complement within the same family. For direct pin-compatible substitution in PNP configurations, verify equivalent voltage and current ratings. No other specific cross-model substitutes are confirmed in public documentation.
