Can you explain more about the area of safe operation?

Latest Updated:09/02/2013

Question:

I have a question about the area of safe operation (SOA).

  • Is there any SOA test data or ratings for continuous pulse?
  • Will SOA destruction not occur as long as continuous pulse is within single-shot SOA?

Answer:

Depending on the product, characteristics of continuous pulse may not be specified. If continuous pulse SOA is not mentioned in the datasheet, then there are no test data or ratings. When using continuous pulse, it is necessary to make sure that the channel temperature (Tch) is not exceeded and that each pulse is within single-shot SOA.
