• Automotive-grade qualification status under AEC-Q101

Single Bipolar Transistors Applications

• Power amplifiers
• Driver circuits

Single Bipolar Transistors Procurement Notes

Verify the specific suffix designation against official documentation to confirm the exact qualification status. The '-AQ' suffix indicates the component is currently undergoing AEC-Q101 qualification rather than holding full compliance. Confirm mechanical dimensions and tape-and-reel specifications prior to integration into automated assembly lines.

Single Bipolar Transistors Selection Notes

Select this component for high-current switching applications requiring low saturation voltage and high linearity. Ensure the design accommodates the 20 W power dissipation limit by providing adequate heatsinking or copper area on the PCB. Verify that the operating junction temperature remains within the specified -55°C to +150°C range during all operational phases.

Single Bipolar Transistors Part Context

This part belongs to the 2SD1815 series of SMD high-current NPN transistors manufactured by Diotec Semiconductor. It shares electrical characteristics with the 2SD1815SR variant but utilizes the TR suffix to denote the taped and reeled packaging format. The series is designed for commercial and industrial grade applications requiring reliable high-power switching capabilities.

Single Bipolar Transistors Replacement Considerations

The 2SD1815SR is an electrically compatible alternative within the same product family. Both variants share identical pinouts and maximum ratings. Differences are limited to the packaging configuration and the specific automotive qualification status indicated by the suffix.
