I am looking at a FDV304P FET. (http://download.siliconexpert.com/pdfs/2004/0615/lib/manual/fsc/ds/fdv304p.pdf)
In the schematic drawing on the datasheet, a diode exists between the Drain and the Source. So,
1) Is the diode to be treated as a normal diode, ie, current can freely flow between the Drain and the Source when Vdrain > Vsource?
2) What is the purpose of this diode?
