a) Thermal resistance characteristics*Simulated values are used for alumina-substrate values
b) Transient thermal resistance characteristics (20 W)
Denka Measuring Method used for the thermal conductivity of substrates


This photograph shows the thermal images with a 4A current applied for 10 seconds (Tr: TO-220). It can be seen that the temperature rise of the "DENKA HITT PLATE" is kept very small thanks to its excellent thermal conductivity.
