DTC123YCA-TP

Overview

The DTC123YCA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a surface-mount SOT-23 package. It integrates biasing resistors to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 200 mW at 25°C. The device features a typical transition frequency of 250 MHz and a minimum DC current gain of 33. The internal resistor configuration consists of R1 with a nominal value of 2.2 kΩ and a resistance ratio (R2/R1) of 4.5.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Built-in biasing resistors eliminate the need for external input components
• RoHS compliant and lead-free finish
• Halogen-free "Green" device meeting environmental standards

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit parts. Confirm the suffix -TP indicates tape-and-reel packaging containing 3000 pieces per reel. Ensure the component meets specific project requirements regarding moisture sensitivity level and flammability ratings before integration.

Selection Notes

Select this component when an NPN digital transistor with integrated biasing is required for space-constrained designs. The SOT-23 package suits surface-mount assembly processes. Consider the 2.2 kΩ base resistor value and 50 V voltage rating to ensure compatibility with the target logic levels and supply voltages within the specified operating temperature range.

Part Context

This part belongs to the DTC123 series of NPN digital transistors produced by Micro Commercial Components. The series is designed for general-purpose switching and amplification tasks where simplified biasing networks are beneficial. The device marking on the package is '62'.

Replacement Considerations

Check pinout compatibility and electrical parameters such as VCEO, IC, and R1 values when substituting. Verify that alternative components meet the same RoHS and halogen-free requirements if environmental compliance is mandatory.
