These components may be used for the overvoltage protection of information & communication technology (ICT) systems and power distribution systems with nominal system voltages up to AC 1 000 V (RMS) and DC 1 500 V. The following PN-junction component technologies are covered:Zener breakdown avalanche breakdown fold-back punch-through forward conduction
