please see www.vishay.com/doc?99912

Notes

• For the assembly on board, we recommend the lead (Pb)-free thermal profile as per J-STD-020C

• Power dissipation is 3.1 W at an ambient temperature of 25 °C when mounted on a double sided copper board using FR4 HTG, 70 μm of

copper, 39 mm x 30 mm x 1.6 mm, with thermal vias
