Hi,
I am measuring case temperature placing the thermocouples on mosfets in the bridge configuration of motor control board. During the motor rotation or power consumption the six power mosfets are getting warm in my experiment and to monitor if the case temperature exceeds rated junction temperature of power mosfet's i placed thermocouples to get the data in degree centigrades. The question is how long we have to let it in running condition? How long we have to wait to check if case temp exceeds jn temp of power mosfet?
