Estimation error of semiconductor devices virtual junction temperature in IEC's aproximate formula

Diagrams were devised which enable the determination of errors in estimating virtual junction temperature of semiconductor devices for a long train of equal amplitude rectangular load power pulses with the IEC-recommended approximate formula. They show that for no semiconductor device the estimation error for virtual junction temperature with IEC-recommended formula exceeds a certain value. IEC's conditions for good approximation proved unnecessary.
