MMBTRA102SS-AQ

Overview

The MMBTRA102SS-AQ is a surface-mount digital PNP transistor manufactured by Diotec Semiconductor, housed in an SOT-23 (TO-236) package. It integrates bias resistors to reduce board space and simplify circuit design. The device features a maximum output voltage of -50 V and a continuous output current of -100 mA, with a total power dissipation of 200 mW at 25°C ambient temperature on a PCB with 3 mm² copper pads. It operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a DC current gain of 50 at -5 V and -10 mA, a transition frequency of 200 MHz, and integrated base and emitter resistors of 10 kOhms each.

Feature Summary

• Integrates dual bias resistors to minimize footprint and simplify driver circuits
• Designed for cost and space savings in commercial and industrial applications
• Compliant with RoHS directives and REACH regulations without exemptions

Applications

• Digital control systems
• Switching applications
• Signal processing circuits

Procurement Notes

Verify the specific suffix designation when sourcing. The -AQ suffix indicates the component is currently undergoing AEC-Q101 qualification rather than holding full compliance certification. Confirm the exact qualification status with the manufacturer or authorized distributors prior to finalizing automotive-grade designs to ensure alignment with project reliability requirements.

Selection Notes

Select this component for PNP switching tasks requiring integrated base drive. Ensure the load current remains below 100 mA and the voltage does not exceed -50 V. Verify that the 10 kOhm internal resistor values match the logic interface levels. Consider the thermal derating curve if operating above 25°C ambient temperature to maintain the 200 mW power dissipation limit safely.

Part Context

This part belongs to the MMBTRA series of SMD digital transistors from Diotec Semiconductor. The series includes variants with different resistor combinations (e.g., MMBTRA101SS through MMBTRA106SS). The MMBTRA102SS specifically utilizes equal 10 kOhm resistors for both base and emitter connections, distinguishing it from other series members with varied ratios.

Replacement Considerations

Cross-reference with other SOT-23 digital PNP transistors featuring similar 10 kOhm/10 kOhm resistor configurations. Verify pinout compatibility and ensure equivalent voltage and current ratings are met before substitution.
