Overview
The MMBTRC105SS-AQ is an SMD digital NPN transistor from Diotec Semiconductor, housed in a SOT-23 (TO-236) package. It integrates bias resistors to reduce component count and board space. Key electrical parameters include a maximum output voltage of 50 V, collector current of 100 mA, and power dissipation of 200 mW at 25°C ambient temperature. The device features a DC current gain of 80 minimum at VO=5V and IO=10mA. Internal resistors are R1=2.2kΩ and R2=47kΩ. Input voltage range is -5V to +12V. Transition frequency is 200 MHz. The suffix -AQ denotes AEC-Q101 qualification for automotive applications.
Feature Summary
- Integrated bias resistor network reduces footprint and assembly costs
- AEC-Q101 qualified for automotive reliability standards
- RoHS compliant and conflict mineral free construction
Applications
- Digital control circuits
- Signal processing switching
- Automotive electronic modules
Procurement Notes
Verify the specific ordering code MMBTRC105SS-AQ against official Diotec documentation to confirm AEC-Q101 qualification status. Ensure supply chain partners provide traceability certificates for automotive grade components. Confirm packaging details match project requirements, as standard tape and reel quantities apply. Validate that the supplier source aligns with authorized distribution channels to guarantee component authenticity and storage condition integrity.
Selection Notes
Select this component when a compact NPN switch with integrated base drive is required. The specific resistor ratio of approximately 0.047 suits applications needing low input drive current relative to output capability. Verify input voltage limits (-5V to +12V) fit the logic interface. Consider the 200mW power dissipation limit and thermal derating curves for PCB layout planning. Compare transition frequency requirements against the 200MHz specification for high-speed switching needs.
Part Context
This part belongs to the MMBTRC10xSS series of digital transistors. Variants differ primarily by internal resistor values and corresponding input voltage ranges. The -AQ suffix specifically indicates automotive qualification under AEC-Q101, distinguishing it from commercial grade versions like the -SS or -Q suffixes. All variants share the same SOT-23 mechanical outline and basic electrical ratings.
Replacement Considerations
Direct substitutes must match the SOT-23 package, NPN configuration, and similar resistor values (R1~2.2k, R2~47k). Verify AEC-Q101 compliance if automotive use is intended. Check input voltage tolerance and current gain specifications to ensure circuit compatibility without redesign.
