DTC124EUAHE3-TP

Overview

The DTC124EUAHE3-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN bipolar junction transistor with internal biasing resistors in a surface-mount SOT-323 package. Key electrical specifications include a collector-emitter breakdown voltage of 50 V, a continuous collector current of 100 mA, and a transition frequency of 250 MHz. The device features a typical base resistor value of 22 kOhms and an emitter resistor of 22 kOhms. It operates within a temperature range of -55°C to +150°C with a maximum power dissipation of 200 mW.

Feature Summary

• Integrates NPN transistor with dual biasing resistors for simplified circuit design
• Automotive-grade qualification compliant with AEC-Q101 standards
• High-frequency operation capability up to 250 MHz
• Extended thermal operating range suitable for demanding environments

Applications

• Switching applications in automotive electronic systems
• Driver circuits for low-power loads requiring pre-biasing
• Logic level translation and interface buffering
• General-purpose switching in consumer electronics

Procurement Notes

Verify the specific suffix HE3 against official MCC documentation to confirm halogen-free status and RoHS compliance details. Confirm the SOT-323 package designation matches the required footprint for PCB layout. Ensure the AEC-Q101 qualification is explicitly stated for the target application environment. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when an NPN configuration with 22k/22k ohm biasing resistors is required in a compact SOT-323 form factor. Compare against similar DTC124 variants if different resistance ratios or packages like SOT-23 are needed. Verify that the 50V rating and 100mA current capacity meet the load requirements. Consider the 200mW power dissipation limit for thermal management in dense assemblies.

Part Context

This part belongs to the DTC124 series of pre-biased transistors from Micro Commercial Components. It shares functional similarities with other members of the family but differs in package type and specific resistance values. The HE3 suffix typically indicates environmental compliance attributes such as halogen-free construction. It serves as a direct replacement for discrete resistor-transistor networks in space-constrained designs.

Replacement Considerations

Direct substitutes include DTC124ECAHE3-TP (SOT-23 package) and DTC124EUA-TP (SOT-323 package without HE3 suffix). Verify pinout compatibility and electrical parameters before substitution. Check if the alternative part holds AEC-Q101 certification if automotive use is intended.
