DTC123JUAHE3-TP

Overview

The DTC123JUAHE3-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN bipolar junction transistor with built-in biasing resistors in a compact SOT-323 surface-mount package. The device features a typical base input resistance of 2.2 kOhms and an emitter-base resistance of 47 kOhms, resulting in a typical resistor ratio of 21. Key electrical specifications include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 200 mW. The DC current gain (hFE) is specified as a minimum of 80 at 10 mA and 5 V. The saturation voltage is typically 300 mV, and the transition frequency reaches 250 MHz. It operates within a temperature range up to +150°C.

Feature Summary

• Integrates NPN transistor with pre-biased resistors for simplified circuit design
• Automotive-grade qualification compliant with AEC-Q101 standards
• Compact SOT-323 surface-mount packaging for space-constrained applications

Applications

• Switching circuits in automotive electronic control units
• Driver stages for low-power loads in vehicle systems
• Logic level translation and buffering in automotive interfaces

Procurement Notes

Verify component authenticity through authorized MCC distributors or certified suppliers. Confirm AEC-Q101 automotive grade status via official datasheets. Check for RoHS compliance and halogen-free packaging requirements. Ensure storage conditions adhere to moisture sensitivity levels. Validate part markings against manufacturer specifications to prevent counterfeits.

Selection Notes

Select this component when an NPN digital transistor with integrated biasing is required for automotive applications. The SOT-323 package suits designs needing small footprint solutions. Verify that the 50V voltage rating and 100mA current capacity meet system demands. Consider the 2.2kOhm base resistance for drive current calculations. Ensure thermal management supports the 200mW power dissipation limit.

Part Context

This part belongs to the DTC123JUA series of NPN digital transistors from MCC. It shares the same pinout and functional characteristics as the non-qualified DTC123JUA-TP variant but includes additional automotive reliability testing. The 'HE3' suffix indicates specific manufacturing attributes related to environmental compliance and package standardization within the MCC portfolio.

Replacement Considerations

The DTC123JUA-TP is a direct functional substitute with identical pinout and electrical parameters, lacking only the automotive qualification. Other DTC123 series variants may offer different resistor values or packages.
