DTC143TUA-TP

Overview

The DTC143TUA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-323 surface-mount package. It integrates a single bias resistor (R1) with a nominal value of 4.7 kΩ, ranging from 3.29 kΩ to 6.11 kΩ. The device supports a maximum collector-emitter voltage (VCEO) and collector-base voltage (VCBO) of 50 V, with a continuous collector current rating of 100 mA. Key electrical characteristics include a DC current gain (hFE) between 100 and 600 at IC=1mA, VCE=5V, and a transition frequency (fT) of 250 MHz. The component features low saturation voltage and cut-off currents, designed for efficient switching applications.

Feature Summary

• Built-in thin-film bias resistors enable inverter circuit configuration without external input components
• Complete isolation of bias resistors allows negative biasing of the input while eliminating parasitic effects
• Simplified operation requiring only on/off condition settings for design ease

Applications

• Inverter circuits
• Switching applications
• Logic interface circuits

Procurement Notes

Verify authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Unauthorized sources lack traceability and quality guarantees. Confirm the RoHS compliant suffix 'P' and tape-and-reel packaging specifications match project requirements before finalizing orders.

Selection Notes

Select this component for designs requiring a compact NPN digital transistor with integrated base resistance. Ensure the 50 V voltage rating and 100 mA current capacity align with circuit demands. Verify that the SOT-323 package dimensions fit the PCB layout constraints and that the 4.7 kΩ internal resistor value suits the required drive conditions.

Part Context

This part belongs to the DTC143 series of NPN digital transistors from Micro Commercial Components. It is specifically packaged in the SOT-323 form factor, distinguishing it from other variants like those in SOT-23 or SC-70 packages within the same product family.

Replacement Considerations

Consult official datasheets for cross-reference compatibility. Potential substitutes may include other NPN digital transistors with similar 50 V ratings and integrated bias resistors, provided pinouts and electrical parameters match exactly.
