Technical Definition

Absorber, Overvoltage, also referenced with federal logistics item name code 21899 - An item specifically designed to absorb and consume surges of voltage such as that resulting across contacts when breaking a circuit having an inductive load or a burst of static across a telephone receiver. it is connected in parallel with the item it is protecting. it may be made up of metallic rectifier cells or semiconductor devices connected back-to-back which may or may not be shunted by a capacitor. it may also be a single rectifier cell or semiconductor device shunted by a capacitor. excludes metallic rectifiers which are rated for rectifying capabilities and all single unit semiconductor devices not shunted by a capacitor. for items perfoming this function by use of voltage sensitive resistors, see resistor, voltage sensitive. see also cutout disk, protective.
