| Summary: | This paper investigates the influence of temperature variation, aging and radiation exposure on over-voltage diode operation. Behaviour of over-voltage diodes in the temperature range from -50 deg C to +150 deg C is examined. Aging is investigated by applying 1000 consecutive double exponential over-voltage pulses to the diode. Radiation effects of a combined neutron/gamma radiation field are analyzed. Volt-ampere characteristic, volt-ohm characteristic, and the value of breakdown voltage are used to characterize over-voltage diode operation, along with the nonlinear coefficient defined nom thy; volt-ampere curve. Over-voltage diodes showed severe impairment of protective characteristics after being exposed to radiation or increased temperature, while on the other hand they proved to be highly resistive to aging. Theoretical interpretation of the observed changes in over-voltage diode behaviour is also provided in the paper. |
