Overview
The DTC123TKAT146 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SMT3 (SOT-346) surface-mount package. It integrates biasing resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance (R1) of 2.2 kOhms and an emitter-base resistance (R2) of 47 kOhms. It operates with a maximum power dissipation of 200 mW and supports a maximum operating temperature of +150°C. The DC current gain (hFE) is specified at a minimum of 80 under test conditions of 10 mA and 5 V.
Feature Summary
- Integrates built-in biasing resistors to eliminate the need for external components in inverter circuits.
- Provides high-density mounting through a compact three-terminal SMT3 surface-mount package.
- Offers stable switching performance with defined current gain characteristics for reliable digital logic interfacing.
Applications
- General-purpose inverter circuits
- Interface driving applications
- Logic level translation
Procurement Notes
Verify the complete ordering part number against official ROHM documentation to ensure correct suffix alignment. Confirm that the specific variant matches the required electrical tolerances and packaging format for your production line. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance status and any recent design changes or obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when a single NPN digital transistor with integrated biasing is required for space-constrained designs. Ensure the 50 V collector-emitter voltage and 100 mA current rating exceed the maximum load requirements of the target application. Verify that the 2.2 kOhm input resistance aligns with the driving source capabilities and desired switching speed specifications.
Part Context
This component belongs to the DTC123 series of digital transistors from ROHM Semiconductor. The series offers various configurations with different resistor values and polarity options. The DTC123TKAT146 specifically denotes the NPN version with standard biasing resistors packaged in the SMT3 form factor, designed for general-purpose switching tasks in consumer and industrial electronics.
Replacement Considerations
