MUR2040 is a Fast Recovery Diode with a short reverse recovery time.As MUR2040 have a lower reverse recovery time than conventional diodes, they are better suited to high-frequency rectification applications.When voltage is applied in a reverse direction, the diode does not withstand voltage until it enters reverse bias. In reverse bias conditions, the current flow for a specific time. This time is known as Reverse Recovery Time (TRR).
Typically, the Reverse Recovery Time (TRR) for a fast recovery diode lies between tens of nano-seconds to 100 nano-seconds. While the reverse recovery time for a conventional diode lies between a few microsecond to tens of microsecond.
