A surge absorber utilizes a varistor electrically connected to a surge absorbing element. The varistor voltage and nonlinearity factor are chosen so that the varistor has a preselected voltage-current characteristic which prevents the varistor from breaking down and short circuiting and resulting in a thermal runaway.
