Overview
The MMBTRC101SS 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 while saving space and cost. Key electrical ratings include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation of 200 mW at 25°C ambient temperature. The device features typical base and emitter resistors of 4.7 kOhms each, with a resistance ratio of 1. It operates within a junction temperature range of -55°C to +150°C and has a transition frequency of 200 MHz.
Feature Summary
- Integrates dual bias resistors to reduce component count and PCB footprint
- Compliant with RoHS directives without exemptions and REACH regulations
- Available in AEC-Q101 compliant (-Q) and qualified (-AQ) automotive grades
Applications
- Digital control circuits
- Signal processing applications
- General switching functions
Procurement Notes
Verify the specific suffix when ordering. Standard versions are commercial grade. Suffixes -Q indicate AEC-Q101 compliance, while -AQ indicates AEC-Q101 qualification for automotive use. Confirm the required reliability grade matches the target application environment before procurement.
Selection Notes
Select this component for NPN switching tasks requiring integrated base drive. Ensure the load current remains below 100 mA and voltage stays under 50 V. Consider the -AQ variant if the design requires automotive-grade reliability standards. Verify thermal management capabilities as power dissipation decreases with rising ambient temperatures.
Part Context
This part belongs to the MMBTRC series of SMD digital NPN transistors from Diotec Semiconductor. The series includes variants with different resistor ratios, such as the MMBTRC102SS through MMBTRC106SS. All share the same SOT-23 package and core electrical characteristics, differing primarily in internal resistor values.
Replacement Considerations
Direct substitutes include other NPN digital transistors with similar 50V/100mA ratings and SOT-23 packaging. Check equivalent resistor values (R1=4.7k, R2=4.7k) and hFE specifications. Automotive replacements must meet AEC-Q101 standards.
