DTC113ZCA-HF

Overview

The DTC113ZCA-HF is an NPN digital transistor manufactured by Comchip Technology, featuring built-in biasing resistors to simplify circuit design. It operates with a collector current of 100 mA and a maximum collector-emitter voltage (VCEO) of 50 V. The device includes an internal base resistor (R1) of 1 kΩ and an emitter-base resistor (R2) of 10 kΩ. Key electrical characteristics include a minimum DC current gain (hFE) of 33 at 10 mA and 5 V, a transition frequency of 250 MHz, and a power dissipation rating of 200 mW. It is housed in a surface-mount SOT-23 package.

Feature Summary

• Built-in biasing resistors eliminate the need for external input components, enabling straightforward inverter circuit configuration.
• Epitaxial planar die construction ensures robust performance within a compact molded plastic case.
• RoHS compliant and halogen-free manufacturing process supports environmentally conscious assembly requirements.

Applications

• Interface circuits requiring simple on/off switching control
• Driver applications for small signal loads
• General-purpose logic level translation

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the DTC113ZCA part number is widely used across multiple semiconductor vendors including ROHM and Micro Commercial Components. Confirm that the Comchip Technology variant matches the required pinout and electrical tolerances for your specific application before finalizing procurement.

Selection Notes

Select this component for designs needing a compact NPN switching solution with integrated biasing. Ensure the 1 kΩ input resistance aligns with the driving source impedance. Verify that the 200 mW power dissipation limit is sufficient for the expected operating conditions and ambient temperature range.

Part Context

This component belongs to the family of pre-biased transistors designed to replace discrete resistor-transistor networks. The 'HF' suffix typically indicates halogen-free compliance. It serves as a direct replacement for standard DTC113Z configurations where environmental compliance is specified.

Replacement Considerations

Direct functional substitutes include DTC113Z variants from other manufacturers such as ROHM or Micro Commercial Components, provided the pinout and electrical ratings are identical. Verify package dimensions and marking codes when cross-referencing.
