PMEG4010EH/EJ/ET
1 A very low V
F
MEGA Schottky barrier rectifiers
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.
[3] Device mounted on an FR4 PCB, single-sided copper, tin-plated, mounting pad for cathode 1 cm

.
[4] Reflow soldering is the only recommended soldering method.
[5] Soldering point of cathode tab.
