MMBTRC102SS-AQ

Overview

The MMBTRC102SS-AQ is an SMD digital NPN transistor manufactured by Diotec Semiconductor, housed in a SOT-23 (TO-236) package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device dissipates up to 200 mW of power and operates within a junction temperature range of -55°C to +150°C. The integrated base resistor (R1) and emitter resistor (R2) are both 10 kOhms with a typical ratio of 1. It features a DC current gain of at least 50 at 5V/10mA and a transition frequency of 200 MHz.

Feature Summary

• Integrates bias resistors to reduce component count and board space
• Compliant with AEC-Q101 automotive qualification standards
• RoHS compliant and free from conflict minerals

Applications

• Digital control circuits
• Switching applications
• Signal processing

Procurement Notes

Verify the specific suffix configuration when ordering. The '-AQ' designation indicates AEC-Q101 qualified status, while '-Q' denotes compliance. Confirm the required packaging format, such as cut tape or reel, matches the production line requirements. Ensure the component meets the specific environmental and reliability standards mandated for the target application before finalizing procurement.

Selection Notes

Select this component for designs requiring a pre-biased NPN transistor with a 10k/10k resistor network. Verify that the 50V voltage rating and 100mA current capacity align with the load requirements. Consider the 200mW power dissipation limit and thermal management needs based on the ambient operating conditions. Ensure the SOT-23 footprint fits the available PCB real estate constraints.

Part Context

This part belongs to the MMBTRC10x series of SMD digital transistors from Diotec Semiconductor. It shares the same physical package and general characteristics as other variants in the family, differing primarily in the internal resistor values. The 'C' in the model number typically signifies the NPN polarity configuration within this product line.

Replacement Considerations

Direct replacements must match the SOT-23 package, NPN polarity, 50V rating, and 10k/10k resistor configuration. Verify pinout compatibility and electrical parameters against competitors like MMBT3904-based digital equivalents or other manufacturers' AEC-Q101 qualified digital transistors.
