DTC114YE-TP

Overview

The DTC114YE-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-523 surface-mount package. It integrates thin-film bias resistors to enable inverter circuit configuration without external input components. Key electrical specifications include a maximum supply voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 150 mW at 25°C. The device features a typical transition frequency of 250 MHz and a DC current gain of 68. Internal resistance values are typically 10 kΩ for R1 and 47 kΩ for R2, yielding a ratio of 4.7.

Feature Summary

• Built-in thin-film bias resistors allow direct inverter circuit configuration without connecting external input resistors.
• Resistors provide complete isolation to facilitate negative biasing of the input and minimize parasitic effects.
• Simplified design process where only On/Off conditions require setting for operation.

Applications

• Inverter circuits
• Buffer circuits
• Switching applications

Procurement Notes

Verify authenticity through MCC or authorized distributors to avoid counterfeit parts. Confirm RoHS compliance via the 'P' suffix designation. Ensure storage conditions align with Moisture Sensitivity Level 1 requirements. Check for UL 94 V-0 flammability rating compliance if required by application standards.

Selection Notes

Select this component when space constraints favor the SOT-523 package over larger alternatives like SOT-23. Consider the 150 mW power dissipation limit relative to ambient temperature derating curves. Verify that the 50 V supply voltage and 100 mA current ratings meet the specific load requirements of the target circuit design.

Part Context

This part belongs to the DTC114 series of pre-biased transistors from Micro Commercial Components. It is designed as a compact solution for replacing discrete resistor-transistor combinations in signal processing and switching roles. The device marking on the package is '64'.

Replacement Considerations

Compatible substitutes include the DTC114YCAHE3-TP (SOT-23 package) and the DTC114TE-TP (SOT-523 package). Verify pinout compatibility and thermal performance differences when substituting between package types.
