Step Recovery Diode (SRD)

The step recovery diodes employes graded where the doping level of the semi-conductive materials is reduced as the pn junction is approached.This produces an abrupt turn off time by

allowing a very fast release of stored charge.When switching from forward to reverse bias.It also allows a rapid re-establishment of forward current when switching from reverse to forward bias.

This diode is used in very high frequency (VHF) and fast Switching Application.
