DTA123JCA-TP

Overview

The DTA123JCA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN transistor with built-in biasing resistors in an SOT-23 surface-mount package. 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. The device features a typical DC current gain of 80 and a transition frequency of 250 MHz. Internal resistance values are defined as R1 = 2.2 kΩ and R2 = 47 kΩ, resulting in a resistance ratio of approximately 21.

Feature Summary

Procurement Notes

Verify the authenticity of the component by checking for the specific device marking E32 on the package. Ensure the ordering suffix matches the required tape and reel configuration. Purchase only from authorized distributors to guarantee traceability and avoid counterfeit parts. Confirm that the RoHS compliance status aligns with project requirements before finalizing procurement.

Selection Notes

Select this component when a compact PNP switching solution with integrated base drive is required. The SOT-23 package is suitable for space-constrained designs. Verify that the -50 V voltage rating and -100 mA current capacity meet the load requirements. Consider the 2.2 kΩ input resistance for driving source impedance compatibility.

Part Context

This part belongs to the DTA123 series of pre-biased transistors from MCC. It is designed as a drop-in replacement for discrete resistor-transistor networks. The 'TP' suffix indicates the standard tape and reel packaging format used for automated assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed using identical pin configurations, voltage ratings, and internal resistance ratios.
