DTC144EKA-TP

Overview

The DTC144EKA-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates an NPN bipolar junction transistor with internal biasing resistors in a compact SOT-323 surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. Internal resistance values are specified as R1 = 47 kOhms and R2 = 47 kOhms. Key electrical characteristics include a DC current gain (hFE) minimum of 100 at 1 mA and 5 V, a saturation voltage of 300 mV max at 1 mA base and 10 mA collector, and a transition frequency of 250 MHz. Power dissipation is rated at 200 mW.

Feature Summary

• Integrates NPN BJT with dual biasing resistors for simplified circuit design
• Optimized for high-speed switching applications with 250 MHz transition frequency
• Low saturation voltage ensures efficient power handling in digital logic interfaces

Applications

• General-purpose digital switching circuits
• Interface between microcontrollers and peripheral devices
• Logic level translation and buffer stages

Procurement Notes

Verify the specific suffix 'EKA' against official MCC documentation to confirm pinout and resistor configuration, as variations exist within the DTC144 family. Ensure compliance with RoHS3 standards if required by the target application environment. Cross-reference datasheets from authorized distributors to validate current production status and packaging options before finalizing procurement plans.

Selection Notes

Select this component when a compact NPN digital transistor with equal base and emitter resistors (47k/47k) is required. Compare against similar packages like SOT-523 or SOT-23 based on board space constraints. Verify that the 50V rating and 100mA current capacity meet the specific load requirements of the intended switching application.

Part Context

This part belongs to the DTC144 series of pre-biased NPN transistors from Micro Commercial Components. The series offers various resistor combinations and package types to suit different design needs. The DTC144EKA-TP specifically utilizes the SOT-323 package, providing a balance between thermal performance and small form factor compared to larger leaded alternatives.

Replacement Considerations

Potential substitutes include other DTC144 series variants from MCC such as DTC144TE-TP or DTC144TUA-TP, provided the resistor network and package compatibility align with the design requirements. Always verify pinout configurations and electrical parameters against the original schematic specifications.
