DTC144TCA-TP

Overview

The DTC144TCA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN bipolar junction transistor with a built-in thin-film bias resistor in a surface-mount SOT-23 package. The device features a collector-emitter breakdown voltage of 50 V and a continuous collector current rating of 100 mA. Electrical specifications include a typical DC current gain (hFE) of 300 at IC=1mA, VCE=5V, and a transition frequency of 250 MHz. The internal resistor R1 has a nominal value of 47 kΩ. The component operates within a temperature range of -55°C to +150°C and is supplied in tape-and-reel packaging containing 3,000 units per reel.

Feature Summary

• Built-in bias resistors enable inverter circuit configuration without external input resistors
• Thin-film resistors provide complete isolation allowing negative biasing of the input
• Halogen-free 'Green' device construction with UL 94 V-0 flammability rated epoxy

Applications

• Inverter circuits requiring simplified design through integrated biasing
• Switching applications where parasitic effects must be minimized
• General-purpose digital logic interfacing and level shifting

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors listed on the manufacturer's website. Counterfeit parts pose significant risks; unauthorized sources do not receive warranty coverage. Confirm RoHS compliance via the "-TP" suffix designation and ensure traceability requirements are met for critical implementations.

Selection Notes

Select this component when a compact NPN solution with integrated base resistance is required. The SOT-23 package suits space-constrained designs. Ensure the 50 V collector-emitter voltage and 100 mA current limits align with the target circuit parameters. Consider the 47 kΩ internal resistor value for appropriate base drive calculations.

Part Context

This part belongs to the DTC144 series of NPN digital transistors from MCC. It utilizes the SOT-23 surface-mount form factor, which is standard for low-power discrete semiconductors. The device marking code for identification is "06". It is distinct from PNP variants or other pin configurations within the broader digital transistor family.

Replacement Considerations

Cross-reference with other NPN digital transistors in the SOT-23 package offering similar 50 V ratings and ~47 kΩ internal base resistance. Verify that substitute components match the hFE range and transition frequency specifications to maintain circuit performance integrity.
