                PMEG4002EB_2 ? NXP B.V. 2010. All rights reserved. Product data sheet Rev. 02 — 13 January 2010 3 of 8 NXP Semiconductors PMEG4002EB 0.2 A very low VF MEGA Schottky barrier rect ifier in SOD523 package 6. Thermal characteristics [1] Device mounted on an FR4 Printed-Circuit Board (PCB), single-sided copper, tin-plated and standard footprint. [2] 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. 7. Characteristics [1] Pulse test: tp ≤ 300 μs; δ≤0.02. Table 6.
