How can I see the SOA when performing switching in continuous pulses?

Latest Updated:03/01/2011

Question:

The data sheet prescribes the safe operating area (SOA) for a single-shot pulse, but not for continuous pulses. How may I see the SOA when performing switching using continuous pulses?

Answer:

When using continuous pulses, you need to calculate the channel temperature (Tch) and make sure that it does not exceed the rated value. Also, you need to check that you are operating within the SOA of each individual pulse.
