	AN9768 Transient Suppression Devices and Principles This application note discusses the two major categories of transient suppressors: a) those that attenuate transients, thus preventing their propagation into the sensitive circuit; and b) those that divert transients away from sensitive loads and so limit the residual voltages.
	AN9769 An Overview of Electromagnetic and Lightning Induced Voltage Transients This application note is an overview of the sources and nature of various transient overvoltages, and the problems that may result.
	EC608 Considerations for Selecting Littelfuse MOVs and Fuses for Industrial Motor Applications This application note discusses the first level considerations for applying both Littelfuse Industrial AC Line Metal Oxide Varistors and associated AC line Fuses with a motor protection example.
	Combining GDTs and MOVs for Surge Protection of AC Power Lines Application Note This application note illustrates how to design high performance, cost-effective surge protection for equipment connected to AC power lines. The role of gas discharge tube (GDT) surge arresters specifically designed for AC power line protection is also be discussed.
