We present a study of thermal effects in Smart Power Electrostatic Discharge (ESD) protection structures by application of a noninvasive infrared backside laserprober technique. The temperature increase in the device active area is obtained from the time resolved measurements of optical phase changes under ESD-like high current stress. Results of temperature distribution and thermal dynamics for different device operation modes are presented.
