Overview
The MMBTRC105SS is a surface-mount digital NPN transistor manufactured by Diotec Semiconductor, housed in an SOT-23 (TO-236) package. It integrates bias resistors to simplify circuit design and reduce component count. Key electrical ratings include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a total power dissipation of 200 mW at 25°C ambient temperature. The device features a typical DC current gain of 80 at 5 V and 10 mA. Internal resistor values are 2.2 kΩ for R1 and 47 kΩ for R2, yielding a resistance ratio of approximately 0.047. The transition frequency is specified at 200 MHz under standard test conditions.
Feature Summary
- Integrates dual bias resistors to minimize board space and assembly complexity
- Designed for high-speed switching and signal processing applications
- Compliant with RoHS directives and REACH regulations without exemptions
Applications

Procurement Notes
Verify the specific ordering suffix when purchasing. Standard versions lack automotive qualification, while suffixes -Q and -AQ denote AEC-Q101 compliance or qualification respectively. Confirm that the required reliability grade matches the application environment before finalizing orders.
Selection Notes
Select this component based on the specific internal resistor configuration. The MMBTRC105SS utilizes a 2.2 kΩ base resistor and a 47 kΩ emitter resistor. Ensure the input voltage range aligns with the datasheet specifications, as other models in the series offer different resistance ratios and input thresholds.
Part Context
This part belongs to the MMBTRx series of SMD digital transistors from Diotec Semiconductor. The series covers various NPN configurations with integrated bias networks, ranging from MMBTRC101SS to MMBTRC106SS. Each variant offers distinct resistor combinations tailored for specific logic interface requirements.
Replacement Considerations
Direct substitutes within the same family include MMBTRC101SS through MMBTRC106SS. Verify that the replacement part shares the identical R1 and R2 values to maintain circuit functionality. Automotive-grade equivalents require matching -Q or -AQ suffixes.
