We have observed an avalanche-like breakdown in the dielectric state of Pbj _ xSnxTe(In) alloys at helium temperatures. This breakdown, which occurs after a time td following the imposition of a strong electric field, leaves the alloy in a new stationary state with a falling volt-ampere characteristic. The lag time td depends on the strength of the electric field and can reach ~ 1 hour.
