DTA143EE-TP

Overview

The DTA143EE-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in the SOT-523 package. It integrates internal bias resistors to simplify circuit design. Key electrical parameters include a maximum supply voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation of 150 mW. The device features a typical input resistance (R1) of 4.7 kΩ with a tolerance range of 3.29 kΩ to 6.11 kΩ. The transition frequency is specified at 250 MHz, and the DC current gain has a minimum value of 30.

Feature Summary

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

Applications

• Inverter circuits
• Switching applications requiring simplified input biasing
• General-purpose digital logic interfacing

Procurement Notes

Verify authenticity by purchasing from MCC or authorized distributors. Counterfeit parts pose significant risks. Ensure the ordering suffix matches the required packaging format. Confirm RoHS compliance status via official documentation before integration into production lines.

Selection Notes

Select this component for designs requiring a compact PNP digital solution with integrated biasing. The SOT-523 package suits space-constrained layouts. Verify that the -50 V rating and -100 mA current capacity align with the specific load requirements of the target application circuit.

Part Context

This part belongs to the DTA143 series of pre-biased transistors. It serves as a compact alternative to discrete BJT and resistor combinations. The device simplifies PCB layout by reducing component count while maintaining reliable switching performance in standard digital environments.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives. Verify that substitute parts match the -50 V rating, -100 mA current limit, and R1 resistance value. Package compatibility must be confirmed for direct replacement.
