UF4007 Specifications
Review UF4007 electrical specifications, operating conditions and package details.
Key specifications
The PN junction briefly carries reverse recovery current while stored charge is removed. The 75 ns limit belongs to a defined test; it is not a universal delay or a complete switching-loss model.
