It refers to the diode's fast reverse recovery capability — significantly reducing switching losses in high-frequency power circuits.

Yes, it is commonly used in solar inverters, especially in boost and H-bridge configurations requiring fast recovery diodes.

While Schottky diodes have lower forward voltage drops, ultrafast recovery diodes like MUR3040 handle higher voltages and temperatures more effectively.

Yes, when properly heatsinked and used in parallel or bridge configurations, it supports high-power SMPS designs.

Silicon Carbide (SiC) diodes offer faster recovery and better high-frequency performance but come at a higher cost.
