Note 3:
BPG­type: Power dissipation is delated by 11.76 mW/°C if device is mounted on PCB and ambient
temperature is above 25°C.
BFG and BFNG­type: Power dissipation is delated by 7.69 mW/°C if device is mounted on PCB and ambient
temperature is above 25°C. With device mounted on glass­epoxy PCB of less than 40% Cu and of
dimensions 50 mm ´ 50 mm ´ 1.6 mm
