A hex fet is a high power MOSFET.  They work by having a metal
oxide capacitor on the gate of it's internal fet.  Hex fets have
a large surface and have thousand of fets in parallel.  anyhow.
The reason they say this is it may build up a charge on the
internal capacitors that exceed it's dielectric strength and
internal voltage limits.  thus it would SELF destruct.
