DTC143ZM-TP

Overview

The DTC143ZM-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-723 surface-mount package. It integrates bias resistors to simplify circuit design, eliminating the need for external input components. Key electrical specifications include a maximum supply voltage of 50V, a continuous output current of 100mA, and a power dissipation rating of 100mW. The device features a typical input resistance (R1) of 4.7kΩ with a resistance ratio (R2/R1) of 10. It operates within a junction temperature range up to 150°C and supports a transition frequency of 250MHz.

Feature Summary

• Built-in thin-film bias resistors enable inverter circuit configuration without external input resistors
• Complete isolation of bias resistors allows negative input biasing and minimizes parasitic effects
• Halogen-free 'Green' device construction with UL 94 V-0 flammability rated epoxy
• Moisture Sensitivity Level 1 classification for simplified storage and handling

Applications

• Inverter circuits
• Interface logic
• Driver stages

Procurement Notes

Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Unverified sources may provide counterfeit parts lacking full traceability. Ensure ordering suffixes match specific packaging requirements, such as the -TP designation for tape and reel quantities. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when space constraints favor the compact SOT-723 footprint over larger packages like SOT-23. The integrated resistor network simplifies layout and reduces bill-of-materials count compared to discrete BJT solutions. Verify that the 100mW power dissipation limit accommodates thermal conditions at elevated ambient temperatures using the provided derating curve.

Part Context

This part belongs to the DTC143 series of pre-biased transistors designed for general-purpose switching applications. The device marking E23 identifies the specific lot and revision on the component body. It represents a standardized solution for replacing multiple discrete components with a single integrated semiconductor device.

Replacement Considerations

Direct substitutes include other NPN digital transistors with similar R1 values and SOT-723 packaging, such as the DTC143ZE-TP or DDTC143ECA-TP. Cross-referencing electrical parameters like VCEO and hFE is required before substitution.
