The 1.5KE110CA Diode is a transient voltage suppressor made by CDIL. This part is designed to protect sensitive electronics from voltage spikes and over-voltage conditions. The diode is designated 1.5kW, 105V, 10A, bidirectional, DO201AD, and comes in an ammo pack package. It is designed to clamp off voltage spikes when they exceed +105V or -105V. This diode is commonly used in power supplies, industrial control systems, communications devices, and any other electronic system susceptible to transient voltage stress.
