DTC115EM-TP

Overview

The DTC115EM-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a silicon epitaxial planar transistor with built-in thin-film bias resistors in a compact SOT-723 package. The device features equal base and emitter-base resistances of 100 kΩ each. 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 200 mW. The component supports surface-mount technology and operates within a storage temperature range of -55°C to +150°C.

Feature Summary

• Integrates NPN bipolar junction transistor with dual built-in bias resistors for simplified circuit design
• Utilizes thin-film resistor technology providing complete isolation and elimination of parasitic effects
• Enables direct inverter configuration without requiring external input resistors

Applications

• Inverter circuits
• Interface logic drivers
• General-purpose switching applications

Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official documentation to confirm packaging type and compliance status. Ensure the selected variant matches the required SOT-723 footprint and thermal characteristics for the target application environment.

Selection Notes

Select this component when space-constrained designs require integrated biasing. Confirm that the 100 kΩ internal resistance values align with the driving source requirements. Verify compatibility with the 50 V supply voltage limit and 100 mA current capacity during peak operation.

Part Context

This part belongs to the DTC115 series of digital transistors from MCC. It serves as a pre-biased solution replacing discrete resistor-transistor networks. The EM designation indicates the specific pinout and package configuration used in modern surface-mount assemblies.

Replacement Considerations

Cross-reference with DTC115EUA or DTC115EE for alternative packages. Verify pinout compatibility before substitution. Check if automotive grade AEC-Q101 certification is required, as standard versions may differ from automotive-rated equivalents.
