what will happen when a SCR is heated.will it turn on the SCR at a value much lower than breakdown voltage?

SUMMARY
Heating a Silicon Controlled Rectifier (SCR) can lead to its turn-on at a lower breakover voltage than specified. The discussion clarifies that SCRs do not operate on a breakdown principle but rather on a breakover principle. Participants emphasize the importance of consulting SCR datasheets to understand temperature dependencies and their effects on performance. Misunderstandings regarding terminology, such as "breakdown" versus "breakover," are addressed to enhance clarity in the discussion.
