DTA123YUA-TP

Overview

The DTA123YUA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-323 surface-mount package. It integrates thin-film bias resistors to enable inverter circuit configuration without external input components. Key electrical parameters include a maximum supply 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, an input resistance (R1) of 2.2 kΩ, and a resistance ratio (R2/R1) of 4.5.

Feature Summary

• Built-in bias resistors facilitate inverter circuit design without requiring external input resistors
• Thin-film resistors provide complete isolation to allow negative biasing of the input
• Elimination of parasitic effects through integrated resistor structure
• Simplified operation where only on/off conditions need to be set

Applications

• Inverter circuits
• Logic level shifting
• Switching applications

Procurement Notes

Verify component authenticity by checking for the specific device marking '52' on the SOT-323 package. Confirm RoHS compliance status via the manufacturer's documentation, as the suffix designation indicates environmental adherence. Ensure sourcing from authorized distributors to maintain traceability and quality standards defined by MCC.

Selection Notes

Select this component when a compact PNP digital solution with integrated biasing is required for space-constrained designs. Consider the -50 V supply voltage limit and -100 mA current capability during circuit planning. Verify that the SOT-323 footprint aligns with the PCB layout requirements and that the thermal performance meets the 200 mW dissipation specification under expected operating conditions.

Part Context

This part belongs to the DTA123 series of PNP digital transistors produced by Micro Commercial Components. The series utilizes thin-film technology for internal resistors, distinguishing it from standard discrete BJT configurations. The 'TP' suffix denotes tape and reel packaging, typically containing 3000 pieces per reel for automated assembly processes.

Replacement Considerations

Cross-reference with other PNP digital transistors in the SOT-323 package having similar -50 V ratings and 2.2 kΩ base resistance. Verify pinout compatibility and electrical characteristics such as hFE and saturation voltage before substitution.
