MMBTRC104SS-AQ

Overview

The MMBTRC104SS-AQ is a surface-mount digital NPN transistor from Diotec Semiconductor, housed in an SOT-23 (TO-236) package. It integrates bias resistors R1 and R2, both rated at 47 kOhms, with a typical resistance ratio of 1. The device supports a maximum collector voltage (VO) of 50 V and a continuous collector current (IO) of 100 mA, with a power dissipation (Ptot) of 200 mW. It features a minimum DC current gain (GI) of 80 at VO = 5 V and IO = 10 mA, and a transition frequency (fT) of 200 MHz. The -AQ suffix indicates AEC-Q101 qualification. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Integrated bias resistor network eliminates external components for simplified circuit design
• AEC-Q101 qualified for automotive-grade reliability standards
• RoHS compliant and free of conflict minerals

Applications

• Digital control circuits
• Switching applications
• Signal processing

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm AEC-Q101 qualification status. Ensure the requested quantity matches standard reel packaging requirements. Confirm that the component meets all necessary environmental compliance standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a single NPN digital transistor with equal base and emitter resistors is required. The 47 kOhm input resistance suits moderate drive currents. Verify that the 50 V collector-emax voltage and 100 mA current limits accommodate the peak load conditions of the target application without exceeding thermal constraints.

Part Context

This part belongs to the MMBTRC10x series of SMD digital transistors. The series offers various resistor combinations within the same SOT-23 footprint. The MMBTRC104 variant specifically provides matched 47 kOhm resistors, distinguishing it from other series members like the MMBTRC101 or MMBTRC102 which feature different resistance values.

Replacement Considerations

Direct substitutes include other MMBTRC104 variants such as MMBTRC104SS or MMBTRC104SS-Q, provided the AEC-Q101 qualification requirement is met by the specific suffix.
