Overview
The DTC144TCAT116 is an NPN digital transistor from the ROHM DTx series, housed in a surface-mount SOT-23 (SST3) package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage of 50V and a continuous collector current of 100mA. The typical input resistance R1 is 47 kΩ. DC current gain (hFE) ranges from 100 to 600 at 1mA. Transition frequency is typically 250MHz. Power dissipation is rated at 200mW on a reference land or 350mW on a ceramic board.
Feature Summary
- Built-in biasing resistor enables inverter circuit configuration without external input resistors.
- Simplifies circuit design by requiring only on/off condition settings for operation.
Applications
- Inverter circuits
- Interface applications
- Driver circuits
Procurement Notes
Verify the specific ordering suffix 'T116' against the manufacturer's datasheet to confirm packaging details such as tape width and reel size. Ensure that the component meets RoHS compliance requirements for your target market. Confirm storage conditions to prevent degradation of solderability before use.
Selection Notes
Select this component when a single NPN digital transistor with a 47kΩ base resistor is required. Verify that the 50V collector-emitter voltage and 100mA current ratings suit the load requirements. Consider the SST3 package dimensions for PCB layout constraints.
Part Context
This part belongs to the ROHM DTC144TCA family of bias resistor built-in transistors. It serves as the NPN counterpart to the PNP DTA144TCA. The T116 suffix indicates the specific taping code and reel size for surface-mount manufacturing processes.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer for equivalent components if sourcing is restricted.
