5. Limiting values
[1] Device mounted on an FR4 Printed-Circuit Board (PCB), single-sided copper, tin-plated and standard
footprint.
[2] Device mounted on an FR4 PCB, single-sided copper, tin-plated, mounting pad for cathode 1 cm2.
6. Thermal characteristics
[1] For Schottky barrier diodes thermal run-away has to
be considered, as in some applications the reverse
power losses PR
are a significant part of the total power
losses. Nomograms for determining the reverse
power losses PR
and I
F(AV)
rating will be av
ailable on request.
