N2  - In this paper the IR mapping is used for the inspection of power transistor KT827B type. On the basis of amplitude and phase temperature images it is possible to observe such phenomena as concentrating of the variable component of collector current and areas of breakdown. The IR amplitude pictures give information about the distribution of dissipated power while the IR phase maps allow separating the electrical phenomena in time independently of its amplitude. The variable component of thermal fields gives more information and higher contrast then the constant one
