SOFT/FAST RECOVERY DIODE
A Soft recovery Diode is a diode where the ratio of Trrr to Trrf is approximately 1 to 3. These diodes are designed to prevent high dI/dt currents from causing high voltage spikes in circuits with inductors, since Voltage = L(dI/dt).
Let us consider that in any circuit there will always be a certain inductance, even if only parasitic.
Recovery fast diodes are used in switching power supply circuits used in DC/DC converters, power factor correction circuits, motor control and other high switching speed PWM applications where diodes are often required capable of quickly restoring an operating point.
"Fast" and "ultrafast" diodes are so called because they stop conducting current in the opposite direction very quickly. "Soft" is a term applied to a subset of always-fast rectifiers that restore the non-conducting state rapidly, but non-abruptly.
