Overview
The MMBTRC106SS-AQ is a surface-mount digital NPN transistor from Diotec Semiconductor, housed in an SOT-23 (TO-236) package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation of 200 mW. The device features a typical DC current gain of 80 at 5 V and 10 mA. Internal resistors are R1 = 4.7 kΩ and R2 = 47 kΩ. It operates within a temperature range of -55°C to +150°C and has a transition frequency of 200 MHz.
Feature Summary
- Integrates bias resistor combinations for cost and space savings
- AEC-Q101 qualified for automotive applications
- Compliant with RoHS, REACH, and Conflict Minerals regulations
Applications
- Digital controls
- Switching circuits
- Signal processing
Procurement Notes
Verify the specific suffix configuration when ordering. The -AQ suffix indicates AEC-Q101 qualification, while -Q denotes compliance. Confirm the required packaging format, such as cut tape or reel, matches the production line requirements. Ensure the component meets the intended reliability standards for the target application environment before finalizing procurement.
Selection Notes
Select this component for designs requiring a pre-biased NPN transistor with integrated base and emitter resistors. The 4.7 kΩ input resistor and 47 kΩ emitter resistor combination suits specific logic interface needs. Consider the 200 mW power dissipation limit and thermal management on the PCB. Verify that the 50 V rating and 100 mA current capacity align with the load requirements.
Part Context
This part belongs to the MMBTRC10x series of SMD digital NPN transistors. The series includes variants with different internal resistor values, such as MMBTRC101SS through MMBTRC106SS. The MMBTRC106SS variant specifically uses a 4.7 kΩ base resistor and a 47 kΩ emitter resistor. The -AQ suffix distinguishes it as an automotive-qualified version within this family.
Replacement Considerations
Check pinout compatibility with existing designs. Verify that substitute components match the 50 V voltage rating, 100 mA current capability, and similar internal resistance ratios. Ensure any replacement also meets AEC-Q101 requirements if the application demands automotive-grade reliability.
