DTA123YCA-TP

Overview

The DTA123YCA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates biasing resistors within an SOT-23 package to simplify circuit design. Key electrical specifications include a maximum supply voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation rating of 200 mW. The device features a typical DC current gain of 33, an input resistance (R1) of 2.2 kΩ, and a transition frequency of 250 MHz. It operates within a junction temperature range up to 150°C and supports storage temperatures from -55°C to 150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Built-in biasing resistors eliminate the need for external components
• Halogen-free 'Green' device compliant with environmental standards
• Moisture sensitivity level 1 for robust handling

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors. Counterfeit parts pose significant risks; unauthorized sources lack traceability and warranty coverage. Confirm the part number includes the -TP suffix for tape and reel packaging containing 3000 pieces per reel. Ensure compliance with RoHS requirements indicated by the 'P' suffix designation.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The SOT-23 package suits surface mount applications. Verify that the -50V supply voltage and -100mA current ratings align with system requirements. Consider the 2.2kΩ input resistance for logic interface compatibility.

Part Context

This component belongs to the DTA123 series of pre-biased transistors. It serves as a complementary counterpart to NPN variants like the DTC123 series. The device is designed for general-purpose switching and amplification tasks where simplified biasing networks are beneficial.

Replacement Considerations

Compatible substitutes include other PNP digital transistors with similar R1 values and SOT-23 packaging. Verify pinout compatibility and electrical parameters such as VCEO and IC before substitution.
