The SOA graph generally assumes an ambient temperature of 25° C, with a junction temperature below 150° C. Over-currents even for a short duration can cause progressive damage to a MOSFET, often with little noticeable …
Webactually what limits the safe operating area since it can happen at a much lower collector current than static latchup, and it depends on the turn-off dv/dt. By staying within the maximum current and safe operating area ratings, static and dynamic latchup are avoided regardless of turn-off dv/dt.
