DTA123JE-TP

Overview

The DTA123JE-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in the SOT-523 surface-mount package. It integrates internal bias 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 150 mW at 25°C. The device features a typical transition frequency of 250 MHz and an input resistance (R1) of 2.2 kΩ with a resistance ratio (R2/R1) of 21.

Feature Summary

• Built-in thin-film bias resistors enable inverter configuration without external input components
• Complete isolation of bias resistors allows for negative input biasing
• Elimination of parasitic effects through integrated resistor design

Applications

• Inverter circuits requiring simplified input stages
• Switching applications utilizing pre-biased configurations
• Digital logic interface circuits

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors listed on their official website. Counterfeit parts pose significant risks; unauthorized sources do not provide warranty coverage or traceability. Ensure the ordering suffix matches the required packaging format, such as tape and reel quantities specified in the manufacturer's documentation.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The SOT-523 package offers a compact footprint suitable for high-density PCB layouts. Consider the -50 V breakdown voltage and -100 mA current capability to ensure compatibility with the target circuit's operational limits and load requirements.

Part Context

This part belongs to the DTA123 series of pre-biased transistors produced by MCC. The 'JE' designation identifies the specific pinout and electrical characteristics within the SOT-523 form factor. The '-TP' suffix indicates the standard tape and reel packaging configuration used for automated assembly processes.

Replacement Considerations

Cross-reference with other PNP digital transistors in the SOT-523 package that offer similar R1 values and voltage ratings. Verify pinout compatibility and thermal performance before substitution.
