With a 2.00 mm aluminum radiation plate, the required area can be determined from Fig. 6. Note that substrate
temperature will vary widely with set internal air temperature, and therefore the rear side of the HIC (the aluminum plate
side) must always be kept below the maximum temperature of 105°C.
HIC Internal Mean Power Dissipation Pd
The internal mean power dissipation of the STK6712BMK4 is primarily due to the current control device, the
regenerating current diode, the current detect resistance and the predriver circuit.
Loss in each excitation mode is:

t1, t2 and t3 are the time modes for the waveform indicated below.
t1: Time for winding current to rise to set current
t2: Time for constant current chopping region
t3: Time from end of phase input signal until inverse current regeneration is complete.
