WebHowever, in devices with bipolar conduction (both holes and electrons), the thermal conductivity is different from electrical conductivity. Thermal conductivity is a critical parameter that determines the maximum power under which the semiconductor device is to be operated. The relationship between thermal resistance and thermal conductivity ... WebBipolar transistors are constructed of a three-layer semiconductor “sandwich” either PNP or NPN. As such, transistors register as two diodes connected back-to-back when tested with a multimeter’s “resistance” or …
