MMBTRA226S

Overview

The MMBTRA226S is a surface-mount digital PNP transistor manufactured by Diotec Semiconductor. It integrates bias resistors within an SOT-23 (TO-236) package to simplify circuit design and reduce component count. The device features a maximum collector-emitter voltage of 50 V, a continuous collector current of 800 mA, and a power dissipation rating of 200 mW. Internal resistor values are 2.2 kΩ for R1 and 10 kΩ for R2. It operates across a junction temperature range of -55°C to +150°C and includes a transition frequency of 200 MHz.

Feature Summary

• Integrates dual bias resistors to minimize board space and assembly costs
• Compliant with RoHS directives without exemptions and REACH regulations
• Designed for commercial and industrial grade applications

Applications

• Digital control circuits
• Signal processing stages
• General switching applications

Procurement Notes

Verify the specific ordering suffix when purchasing. Standard versions are designated as commercial/industrial grade. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm these suffixes match project requirements before procurement, as they define the reliability standard rather than changing the electrical function.

Selection Notes

Select this component for designs requiring a PNP digital transistor with integrated biasing in a compact SOT-23 footprint. Ensure the required input resistance ratio aligns with the 2.2 kΩ and 10 kΩ internal configuration. Verify that the 50 V output voltage and 800 mA current ratings exceed the maximum load conditions expected in the target application.

Part Context

This part belongs to the MMBTRA22x series of SMD digital PNP transistors from Diotec Semiconductor. The series provides various combinations of internal bias resistors to suit different logic drive requirements. All members share the same SOT-23 mechanical outline and core electrical characteristics, differing primarily in their internal resistor values.

Replacement Considerations

Compatible substitutes include other SOT-23 packaged digital PNP transistors with similar 50V ratings and integrated bias networks. Verify pinout compatibility and ensure the replacement's internal resistor values match the 2.2kΩ/10kΩ configuration to maintain circuit performance.
