Switch diode principle

Semiconductor diode guides switch is equivalent to closing when connecting (circuit puts through) , switch is equivalent to opening when ending (circuit is cut off) , so diode can make switch use. Switch diode is to use the diode that makes switch use technically, it by guide turn into end or by end turn into guide a needs time is shorter than general diode, have the series such as 2AK, 2DK commonly, basically use in computer, pulse and switch circuit.
