Procurement Notes
Verify the specific suffix when ordering; standard versions are commercial grade, while suffixes like -Q indicate AEC-Q101 compliance and -AQ indicates AEC-Q101 qualification. Confirm the exact resistor value required for the design, as the datasheet lists 4.7 kΩ for this specific part number. Ensure the procurement documentation matches the requested automotive or commercial reliability grade.
Selection Notes
Select the MMBTRC110SS for designs requiring a compact NPN digital transistor with a 4.7 kΩ base resistor. Verify that the 100 mA continuous current and 50 V voltage ratings meet the circuit requirements. Consider the thermal resistance of less than 420 K/W and the 200 mW power dissipation limit when designing the PCB layout for adequate heat management.
Part Context
This component belongs to the MMBTRC110SS...MMBTRC114SS series of SMD Digital NPN Transistors produced by Diotec Semiconductor. The series offers various resistor values to suit different logic interface needs while maintaining the same physical footprint and general electrical limits.
Replacement Considerations
Check for equivalent parts from other manufacturers offering NPN digital transistors in SOT-23 packages with similar 4.7 kΩ input resistors and matching voltage/current ratings.
