DTC123EE-TP

Overview

The DTC123EE-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-523 surface-mount package. It integrates internal bias resistors, with both R1 and R2 specified at 2.2 kOhms. Key electrical ratings include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and power dissipation of 150 mW. The device features a DC current gain (hFE) minimum of 20 and a transition frequency of 200 MHz. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Integrates NPN bipolar junction transistor with pre-biased base and emitter resistors for simplified circuit design.
• Constructed as a halogen-free 'Green' device compliant with RoHS standards and UL flammability ratings.
• Designed for high-frequency applications with a transition frequency up to 200 MHz.

Applications

• Switching circuits requiring integrated biasing components.
• High-speed logic interface buffering.
• General-purpose amplification stages.

Procurement Notes

Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Unverified sources may supply counterfeit parts lacking full traceability. Ensure ordering suffixes match specific packaging requirements such as tape and reel quantities. Confirm compliance with environmental regulations like RoHS before integration into final assemblies.

Selection Notes

Select this component when a compact NPN solution with fixed internal biasing is required. The SOT-523 package suits space-constrained designs. Verify that the 2.2 kOhm resistor values align with the target drive current and input voltage levels. Ensure the 50V breakdown voltage exceeds the maximum circuit operating voltage to prevent device failure.

Part Context

This part belongs to the DTC123 series of single NPN digital transistors. It shares the SOT-523 form factor with other variants but differs in internal resistor ratios. The 'TP' suffix indicates RoHS compliance and lead-free finish. It serves as a direct replacement for discrete resistor-transistor networks in similar packages.

Replacement Considerations

Check pinout compatibility and internal resistor values against existing designs. Verify thermal resistance characteristics if operating near maximum power limits. Ensure voltage and current ratings meet or exceed original specifications.
