www.vishay.comReverse recovery time, trr The time required for the current to reach a specified reverse current, iR (normally 0.25 A), after instantaneous switching from a specified forward current IF (normally 0.5 A) to a specified reverse current IR (normally 1.0 A). Reverse recovery charge, Qrr The charged stored within the diode when instantaneous
NX5P3290 - USB PD and Type-C current-limited power switch
www.nxp.comA fast RCP recovery circuit has been added to the switch to prevent any reverse current flowing back to power source at all times. When exiting from reverse current protection state, the power MOSFET will turn on within 50 us. The fast RCP recovery ensures the voltage on VBUS doesn’t drop too much in a power source swap application.

membranes.comPERMEATE RECOVERY RATE (CONVERSION) Permeate recovery is another important parameter in the design and operation of RO systems. Recovery or conversion rate of feed water to product (permeate) is defined by Equation 9. R = 100% * (Qp/Qf) (9) where R is recovery rate (in %), Qp is the product water flow rate, and Qf is the feed water flow rate.
