Overview
The MMBTRC118SS-AQ is an SMD digital NPN transistor from Diotec Semiconductor, housed in a SOT-23 (TO-236) package. It integrates bias resistors to simplify circuit design and reduce component count. The device features a maximum output voltage of 50 V, a continuous output current of 100 mA, and a power dissipation rating of 200 mW at 25°C ambient temperature. It operates within a junction temperature range of -55°C to +150°C. The specific resistor combination includes R1 of 2.2 kΩ and R2 of 10 kΩ. The suffix '-AQ' indicates AEC-Q101 qualification for automotive applications.
Feature Summary
- Integrates bias resistor combinations to save space and cost
- AEC-Q101 qualified for automotive reliability standards
- Compliant with RoHS, REACH, and Conflict Minerals regulations
Applications
- Digital controls
- Switching circuits
- Signal processing
Procurement Notes
Verify the exact ordering code matches the required AEC-Q101 qualification level. Confirm the integrated resistor values align with the target circuit design requirements. Ensure the SOT-23 package footprint is compatible with the PCB layout. Check for any specific handling or storage conditions mandated by the manufacturer's datasheet.
Selection Notes
Select this component when a compact NPN switching solution with built-in biasing is required. The 2.2 kΩ input resistor suits moderate drive currents. Verify that the 50 V collector-emitter voltage exceeds the maximum circuit voltage. Consider the 200 mW power dissipation limit under expected operating temperatures.
Part Context
This part belongs to the MMBTRCx series of surface mount digital transistors. The series offers various resistor combinations for different logic levels. The MMBTRC118SS variant specifically pairs a 2.2 kΩ base resistor with a 10 kΩ emitter resistor. The -AQ suffix denotes automotive-grade qualification beyond standard commercial grades.
Replacement Considerations
Direct substitutes include other MMBTRC118SS variants from Diotec without the AQ suffix if automotive qualification is not critical. Cross-manufacturer equivalents must match the SOT-23 package, 50 V rating, and identical 2.2 kΩ/10 kΩ resistor network.
