Diode variation
The planar structure and the platinum doped life time
control, guarantee the best overall performance,
ruggedness and reliability characteristics.
These devices are intended for use in the output
rectification stage of SMPS, UPS, DC/DC converters as well
as freewheeling diode in low voltage inverters and chopper
motor drives.
Their extremely optimized stored charge and low recovery
current minimize the switching losses and reduce over
dissipation in the switching element and snubbers.
