Abstract
AbstractThe magnetic and conduction properties of certain ferrites (referred to as temperature‐sensitive magnetic semiconductors (TMS)) exhibit marked temperature dependence. The temperature dependence of the resistance of a TMS is similar to that of a semiconductor thermistor at low voltage. At higher voltages, three regions are observed in the symmetric, bidirectional characteristics. These are a cutoff state, a negative resistance state and an “on” state.Therefore, a TMS can act as a multifunction magnetic semiconductor device which can be used to satisfy thermistor and bidirectional diode characteristics. Application of TMS diodes for their ability to handle overvoltage and overheating is discussed.
