Overview
The MMBTRC101SS-AQ is a surface-mount digital NPN transistor manufactured by Diotec Semiconductor. It integrates bias resistors within an SOT-23 (TO-236) package to reduce component count and board space. The device features a collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation of 200 mW. Internal resistors R1 and R2 are both 4.7 kOhms with a typical ratio of 1. It operates within a junction temperature range of -55°C to +150°C and has a transition frequency of 200 MHz. The suffix -AQ indicates AEC-Q101 qualification.
Feature Summary
- Integrated bias resistor network for simplified circuit design
- AEC-Q101 qualified for automotive reliability standards
- RoHS compliant and free from conflict minerals
Applications
- Digital control circuits
- Signal processing applications
- General switching functions
Procurement Notes
Verify the specific ordering suffix when purchasing. The suffix -AQ denotes AEC-Q101 qualification, while other suffixes like -Q indicate compliance without full qualification. Confirm that the required automotive grade matches the project specifications before finalizing orders.
Selection Notes
Select this component for designs requiring a pre-biased NPN transistor in a compact SOT-23 footprint. Ensure the 4.7 kOhm internal resistance values align with the drive requirements. Verify that the 50 V rating and 100 mA current limits accommodate the maximum expected load conditions.
Part Context
This part belongs to the MMBTRC series of SMD digital NPN transistors produced by Diotec Semiconductor. The series includes variants with different resistor combinations, such as the MMBTRC102SS and MMBTRC103SS. The MMBTRC101SS-AQ specifically provides equal 4.7 kOhm resistors and meets automotive qualification standards.
Replacement Considerations
Check for other MMBTRC series parts if different resistor ratios are needed. Verify pinout compatibility with the SOT-23 package. Ensure any substitute also meets AEC-Q101 requirements if automotive use is intended.
