LITTELFUSE MOV 200 V 100 80 60 SILICON TRANSIENT SUPPRESSION DIODE Electron Irradiation A Littelfuse MOV and a silicon transient suppression diode were exposed to electron irradiation. The V-I curves, before and after test, are shown in Figure 1. It is apparent that the Littelfuse MOV was virtually unaffected, even at the extremely high dose of 108 rads, while the silicon transient suppression diode showed a dramatic increase in leakage current. 40 PRE TEST 108 RADS, 18MeV ELECTRONS 20 108 106 104 CURRENT (A) FIGURE 1.

The selected devices were equal in area. Figure 2 shows the clamping voltage response of the MOV and the zener to neutron irradiation to as high as 1015 N/cm2 . It is apparent that in contrast to the large change in the zener, the MOV is unaltered. At highercurrents where the MOV’s clamping voltage is again unchanged, the zener device clamping voltage increases by as much as 36%. 300 1.5K 200 INITIAL 200 VARISTOR V130A2 INITIAL A 10 15 T 100 80 VOLTS 60 50 40 30 20 BREAKDO WN VOLTAGE SATURATION CURRENT I FORWARD BIAS V REDUCTION IN FAILURE STRESSHOLD BY RADIAL SECONDARY BREAKDO WN 1.5K 200 AT 10 12 REVERSE BIAS FIGURE 3.

At higher reverse voltage VBO (breakdown voltage),the current increases rapidly as the electrons are either pulled by the electric field (Zener effect) or knocked out by other electrons (avalanching). A further increase in voltage causes the device to exhibit a negative resistance characteristic leading to secondary breakdown. This manifests itself through the formation of hotspots, and irreversible damage occurs. This failure threshold decreases under neutron irradiation for zeners, but not for Zinc Oxide Varistors. FIGURE 2. V-I CHARACTERISTIC RESPONSE TO NEUTRON IRRADIA TION FOR MOV AND ZENER DIODE DEVICES Counterclockwise rotation of the V-I characteristics is observed in silicon devices at high neutron irradiation levels; in other words, increasing leakage at low current levels and increasing clamping voltage at higher current levels. The solid and open circles for a given fluence represent the high and low breakdown currents for the sample of devices tested. Note that there is a marked decrease in current (or energy) handling capability with increased neutron fluence. Failure threshold of silicon semiconductor junctions is further reduced when high or rapidly increasing currents are applied. Junctions develop hot spots, which enlarge until a short occurs if current is not limited or quickly removed. The characteristic voltage current relationship of a PN-Junction is shown in Figure 3. Gamma Radiation Radiation damage studies were performed on type V130LA2 varistors. Emission spectra and V-I characteristics were collected before and after irradiation with 106 rads Co60 gamma radiation. Both show no change, within experimental error, after irradiation. 152 w w w. l i t t e l f u s e . c o m Varistor Products Aerospace and Military High Reliability Varistors Commercial Item Descriptions The General Services Administration has authorized the use of the Commercial Item Description (CID) for all government agencies.
