=25C before surge.
[2] Device mounted on an FR4 Printed-Circuit Board (PCB), single-sided copper, tin-plated and standard
footprint.
6. Thermal characteristics
[1] For Schottky barrier diodes thermal runaway has to be considered, as in some applications the reverse
power losses P
R
are a significant part of the total power losses.
[2] Device mounted on an FR4 PCB, single-sided copper, tin-plated and standard footprint.
Table 5. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
