DTA123JKA-TP

Overview

The DTA123JKA-TP is a single PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates internal biasing resistors within an SOT-346-3 surface-mount package. Key electrical specifications include a collector-emitter breakdown voltage of -50 V and a continuous collector current of -100 mA. The device features a typical base resistor (R1) of 2.2 kOhms and an emitter resistor (R2) of 47 kOhms, resulting in a standard resistor ratio of 21. It operates with a maximum power dissipation of 200 mW and supports a transition frequency up to 250 MHz.

Feature Summary

• Integrates dual biasing resistors for simplified circuit design
• Optimized for high-speed switching applications
• Designed for low-voltage logic interface compatibility

Applications

• General-purpose switching circuits
• Logic level translation interfaces
• Driver stages for small-signal loads

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm pinout and electrical tolerances. Ensure the sourcing channel provides valid manufacturer traceability. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required. Compare the 2.2 kOhm input resistance against alternative models if different drive currents are needed. Verify that the SOT-346-3 footprint matches the target PCB layout constraints.

Part Context

This part belongs to the DTA123 series of pre-biased transistors from Micro Commercial Components. It serves as a PNP counterpart to NPN variants like the DTC123 series. The JKA suffix typically denotes the specific packaging and pin configuration used for surface-mount assembly.
