Temperature variation effects on the switching characteristics of bipolar mode FETs (BMFETs)

The switching performance of a bipolar mode FET (BMFET) is examined and measured over a temperature range from -184 degrees C to +197 degrees C. Data are presented which show the temperature variation of the rise and fall times, for both the current and voltage; the measured temperature dependence of the forward voltage drop is also presented. These data show that overall device switching performance is not improved for low temperature operation and is degraded at temperatures above room temperature.<>
