Some Temperature Aspects of MOV Materials.
Abstract
The parameters N and Vc enter into the curves of the DD GE-MOV(TM) material as functions of temperature in the range from 0 to 200 C, where the I-V curves are defined as I = Io times (V/Vc) to the Nth power. Both N and Vc are strongly temperature-dependent; the slopes of Vc and N are almost the same in the region above 50 C. At about 50 C, both N and Vc show a distinct break in otherwise smooth curves. The breaks in these curves probably indicate some internal changes in the material. The simple computer simulation of the output voltage using the equivalent circuit of the MOV material shows that the temperature effects of Vc and N tend to cancel each other, thus providing reasonable clamping capability throughout the whole temperature range.
