Description

• Applications: These diodes are designed for use in static electric power converters as well as other DC and AC units operating on industrial or high frequency, often requiring short reverse recovery times and a high value of surge reverse power dissipation. Operation of avalanche diodes is based on the effect of reversible breakdown of the pn junction upon application of reverse voltage. As soon as the voltage exceeds a specific value, the current flowing throuh the avalanche diode shraply increases while the voltage remains unchanged.
