MMBTRC102SS

Overview

The MMBTRC102SS 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. Key electrical parameters include a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device features a typical DC current gain of 50 at 10 mA and 5 V, with a transition frequency of 200 MHz. Internal resistors R1 and R2 are both 10 kOhms. Power dissipation is rated at 200 mW, operating within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates bias resistor combinations for cost and space savings
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Applications

• Digital controls
• Switching applications
• Signal processing

Procurement Notes

Verify the specific suffix when ordering. Standard versions lack automotive qualification. Suffixes -Q indicate AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm these requirements against the target application's reliability standards before procurement.

Selection Notes

Select this component for standard commercial or industrial grade applications requiring a single NPN digital transistor. Ensure the required input resistance matches the 10 kOhm configuration provided by the MMBTRC102SS variant. Verify that the 50V voltage rating and 100mA current capacity meet the circuit load requirements.

Part Context

This part belongs to the MMBTRx series of SMD Digital NPN Transistors from Diotec Semiconductor. The series includes variants with different internal resistor values, such as MMBTRC101SS through MMBTRC106SS. All share the same physical package and general electrical ratings but differ in their integrated bias resistor configurations.

Replacement Considerations

Direct substitutes must match the SOT-23 package, NPN polarity, 50V/100mA ratings, and 10kΩ/10kΩ internal resistor ratio. Check datasheets for equivalent transition frequencies and saturation voltages.
