DTC114YCA-HF

Overview

The DTC114YCA-HF is an NPN digital transistor manufactured by Comchip Technology, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. The device includes an input resistor (R1) of 10 kΩ and an emitter-base resistor (R2) of 47 kΩ. Power dissipation is rated at 200 mW. It utilizes the SOT-23 surface-mount package and complies with RoHS standards.

Feature Summary

• Integrated biasing resistors eliminate the need for external input components in inverter circuits.
• Epitaxial planar die construction ensures reliable performance in small signal applications.
• RoHS compliant and halogen-free manufacturing process.

Applications

• Inverter circuits
• Switching applications
• Logic interface circuits

Procurement Notes

Verify the specific suffix 'HF' indicates Halogen-Free compliance as per manufacturer documentation. Confirm the package type is SOT-23 and check for automotive qualification status, as standard versions may not be suitable for vehicle equipment. Ensure the ordering code matches the exact resistor values and polarity required for the design.

Selection Notes

Select this component when an NPN digital transistor with 10 kΩ input resistance and 47 kΩ emitter-base resistance is required. The 50 V rating and 100 mA current capacity suit general-purpose switching tasks. Verify that the SOT-23 package dimensions fit the PCB layout constraints and that the thermal dissipation requirements are within the 200 mW limit.

Part Context

This part belongs to the DTC114 series of digital transistors from Comchip Technology. Similar variants include DTC114ECA-HF and DTC114YE, which may differ in package style or specific resistor ratios. The DTC114YCA-HF specifically denotes the NPN polarity with the associated internal resistor configuration and halogen-free certification.

Replacement Considerations

Cross-reference with DTC114ECA-HF for similar electrical characteristics but verify package compatibility. Check ROHM DTD114EF for functional equivalents, noting potential differences in current ratings and packaging. Always validate pinout and thermal performance before substitution.
