 I got bitten by Siliconix when trying to use the
 VN10KM as a direct replacement for a JFET bipolar
 analogue switch. The presence of a shunt body diode
 is not acknowleged on any Siliconix VMOS data ***,
 but there is a mention in one of their app notes.

 A similar situation exists with Zetex DMOS Fets.
 There is no explicit mention of a body diode in the
 process.... you have to notice that some data sheets
 carry an added a Source-Drain Diode spec.
