DTC143EE-TP

Overview

The DTC143EE-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN transistor with thin-film bias resistors in a SOT-523 surface-mount package. 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 typical transition frequency of 250 MHz and an input resistance (R1) of 4.7 kΩ. It operates within a junction temperature range up to 150°C and supports negative input biasing.

Feature Summary

• Built-in thin-film bias resistors enable inverter circuit configuration without external input components
• Complete isolation of internal resistors allows for negative biasing of the input terminal
• Halogen-free construction with UL 94 V-0 flammability rated epoxy
• Moisture Sensitivity Level 1 classification

Applications

• Inverter circuits requiring simplified input resistor connections
• General-purpose switching applications utilizing on/off condition control
• High-frequency signal processing utilizing 250 MHz transition frequency

Procurement Notes

Verify authenticity through MCC or authorized distributors due to counterfeiting risks. Confirm RoHS compliance via the "-TP" suffix designation. Ensure storage conditions align with Moisture Sensitivity Level 1 requirements. Check datasheet revisions for potential parameter updates before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN digital switch with integrated biasing is required. The SOT-523 package suits space-constrained designs. Verify that the 100 mA collector current and 50 V breakdown voltage meet circuit demands. Consider the 4.7 kΩ input resistance for driving interface compatibility.

Part Context

This part belongs to the DTC143EE series of NPN digital transistors. It is distinct from other variants by its specific integration of thin-film resistors and SOT-523 packaging. The series focuses on simplifying digital logic interfaces by eliminating external biasing networks while maintaining standard switching performance characteristics.

Replacement Considerations

Direct substitutes must match the NPN polarity, SOT-523 package, and 4.7 kΩ R1 value. Verify equivalent VCEO, IC, and PD ratings. Cross-reference transition frequency and saturation voltage if high-speed switching is critical. Ensure compatible thermal management for 150 mW dissipation.
