Product data sheet Rev. 02 — 15 April 2010 3 of 14 NXP Semiconductors PMEG4010ER 1 A low VF MEGA Schottky barrier rectifier [1] Device mounted on a ceramic PCB, Al2O3, standard footprint. [2] Tj =25°C prior to surge. [3] Reflow soldering is the only recommended soldering method. [4] Device mounted on an FR4 PCB, single-sided copper, tin-plated and standard footprint. [5] 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 runaway has to be considered, as in some applications the reverse power losses PR are a significant part of the total power losses. [2] Reflow soldering is the only recommended soldering method. [3] Device mounted on an FR4 PCB, single-sided copper, tin-plated and standard footprint.
