• Is it possible to drive the TR beyond the maximum ratings, even for a moment? 
    • No. Operation above the maximum ratings will most likely result in breakdown or, at the very least, deterioration (i.e. hFE drop). Please refer to the SOA (Safe Operating Area) for single pulse operation. For, continuous pulse situations, calculation of the power and die temperature are required.
      Please refer to ROHM’s website for more information (e.g. derating curves).
