DTA143ZE-TP

Overview

The DTA143ZE-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in the SOT-523 surface-mount package. It integrates internal bias resistors, specifically R1 at 4.7 kΩ and R2 at 47 kΩ, to facilitate inverter circuit configurations without external components. 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. The device features a transition frequency of 250 MHz and a minimum DC current gain of 80.

Feature Summary

• Built-in thin-film bias resistors enable inverter circuit configuration without connecting external input resistors.
• Complete isolation of bias resistors allows negative biasing of the input while eliminating parasitic effects.
• Halogen-free construction with epoxy meeting UL 94 V-0 flammability ratings.

Applications

• Inverter circuits requiring simplified design through integrated biasing.
• Switching applications where only on/off conditions need to be set.
• High-frequency signal processing utilizing the specified transition frequency.

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit parts. Confirm RoHS compliance via the 'TP' suffix designation. Ensure storage conditions adhere to Moisture Sensitivity Level 1 standards. Check for specific halogen-free certifications if required by environmental regulations.

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 supply voltage and -100 mA current limits align with system requirements. Consider the 150 mW power dissipation limit when calculating thermal performance at elevated ambient temperatures.

Part Context

This part belongs to the DTA143 series of pre-biased transistors. It utilizes the SOT-523 footprint, distinguishing it from larger packages like SOT-23. The device marking E13 identifies the specific revision and manufacturing batch within the MCC product line.

Replacement Considerations

Cross-reference with other PNP digital transistors in the SOT-523 package. Verify pinout compatibility (IN, OUT, GND) and ensure equivalent resistance values for R1 and R2 are maintained for identical circuit behavior.
