DTC123YCAHE3-TP

Overview

The DTC123YCAHE3-TP is a single NPN digital transistor manufactured by Micro Commercial Components. It integrates an internal base resistor of 2.2 kOhms within a compact SOT-323-3 surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a power dissipation rating of 200 mW. It features a minimum DC current gain (hFE) of 80 at 10 mA and 5 V, and a saturation voltage of 300 mV under specified conditions. The component operates across a temperature range from -55°C to +150°C.

Feature Summary

• Integrates a 2.2 kOhm base resistor for simplified circuit design
• High thermal stability with operation up to +150°C junction temperature
• Automotive-grade qualification compliant with AEC-Q101 standards

Applications

• Switching applications in automotive electronic systems
• General-purpose digital logic interfacing
• Low-power signal switching circuits

Procurement Notes

Verify the specific suffix HE3-TP against official MCC documentation to confirm lead-free compliance and RoHS status. Confirm the SOT-323-3 package type matches the target PCB footprint. Ensure the supplier provides valid traceability data for automotive-grade components requiring AEC-Q101 certification. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit risks.

Selection Notes

Select this component when a compact NPN digital switch with integrated biasing is required. The 2.2 kOhm internal resistor simplifies drive circuitry compared to discrete BJT configurations. Verify that the 100 mA current limit and 50 V voltage rating suit the load requirements. Consider the SOT-323-3 package dimensions for space-constrained designs.

Part Context

This part belongs to the DTC123 series of pre-biased transistors from Micro Commercial Components. It shares functional similarities with other NPN digital transistors but is distinguished by its specific 2.2 kOhm base resistance and SOT-323-3 packaging. The HE3-TP suffix indicates environmental compliance features consistent with the manufacturer's product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative digital transistors based on pinout, voltage ratings, and internal resistance values before substitution.
