Additional Details

The key electrical characteristics of the SD100 varistor include its varistor voltage, surge current capability, and capacitance. The varistor voltage specifies the voltage at which the varistor starts to conduct significantly, effectively clamping the voltage. The surge current capability indicates the maximum surge current the varistor can withstand without damage. Its relatively fast response time allows it to quickly react to transient events. The SD100 is commonly used in automotive applications to protect sensitive electronics from voltage spikes and surges that can occur in the harsh automotive environment. Proper selection of the varistor requires careful consideration of the application's voltage and current requirements to ensure adequate protection.
