Overview
The DTC144ECA-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates bias resistors within an SOT-23 package to simplify circuit design. Key electrical specifications include a supply voltage of 50 V, output current of 100 mA, and power dissipation of 200 mW. The typical input resistance R1 is 47 kΩ with a resistance ratio R2/R1 of 1.0. Transition frequency reaches 250 MHz, while DC current gain is 68. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Built-in thin-film bias resistors enable inverter configuration without external input components.
- Complete isolation of internal resistors allows for negative biasing of the input terminal.
- Elimination of parasitic effects through integrated resistor architecture simplifies device operation.
Applications
- Inverter circuits requiring simplified input stages
- Switching applications utilizing pre-biased configurations
- Digital logic interface circuits
Procurement Notes
Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit parts. Confirm RoHS compliance via the 'P' suffix designation. Ensure storage conditions adhere to Moisture Sensitivity Level 1 standards. Validate component traceability against official documentation before integration into production systems.
Selection Notes
Select this component when designing circuits that require built-in biasing to reduce external component count. Verify that the 50 V supply voltage and 100 mA output current meet system requirements. Consider the 200 mW power dissipation limit and thermal derating characteristics for high-temperature environments.
Part Context
This part belongs to the DTC144ECA series of NPN digital transistors. It utilizes the SOT-23 surface-mount package. The device marking is '26'. It is supplied in tape and reel packaging containing 3,000 pieces per reel.
Replacement Considerations
Cross-reference with other NPN digital transistors featuring similar 47 kΩ input resistance and SOT-23 packaging. Verify pinout compatibility and electrical parameter alignment before substitution.
