DTC124EKA-TP

Overview

The DTC124EKA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single base resistor (R1) of 22 kOhms within a compact SOT-323 package. The device supports a maximum collector-emitter voltage (Vceo) of 50 V and a continuous collector current (Ic) of 100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 68 at 5 mA and 5 V, and a saturation voltage (Vce(sat)) maximum of 300 mV at 500 µA base current and 10 mA collector current. The component operates with a transition frequency of 200 MHz and handles a maximum power dissipation of 150 mW.

Feature Summary

• Integrates a 22 kOhm base resistor for simplified circuit design
• Provides high-speed switching capabilities suitable for logic interfacing
• Offers low saturation voltage to minimize power loss during conduction

Applications

• Logic level shifting between different voltage domains
• Driver circuits for small-signal loads and relays
• Switching applications in portable electronic devices

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm pinout compatibility and internal resistance values. Ensure the selected variant matches the required package type and thermal specifications for the target application environment.

Selection Notes

Select this component when a pre-biased NPN solution is required to reduce board space and external component count. Compare the 22 kOhm input resistance against other series variants to ensure proper drive current requirements are met by the upstream logic source.

Part Context

This part belongs to the DTC124 series of digital transistors from Micro Commercial Components. The series offers various configurations including dual-resistor and single-resistor options across multiple packages such as SOT-23 and SC-70, providing flexibility for different density and performance needs.

Replacement Considerations

Direct substitutes include the DTC124XE-TP and DTC124EUA-TP from MCC, which share similar electrical profiles but differ in package dimensions. Cross-manufacturer equivalents should be verified for matching hFE ranges and Vce(sat) limits.
