Procurement Notes
Verify the active status and specific datasheet version before procurement, as component availability and specifications may change. Confirm that the 60 V breakover voltage and nanosecond switching characteristics align with your circuit design requirements. Ensure compatibility with your system's thermal and electrical constraints.
Selection Notes
Select the GA300 when nanosecond switching speed is critical and low voltage operation around 60 V is required. Consider the low gate trigger current and voltage for drive circuit simplicity. Evaluate if the planar structure meets your reliability standards for commercial use compared to other SCR technologies.
