REQ. MOSFET without body diode

[flatulent]

mosfet without diode

Can anyone suggest a currently availabe MOSFET that does not have the usual build in drain-source body diode? I need to switch a HF signal of several tens of volts.

Many years ago they had such diodeless devices, but all the ones I look at now have the diode.

There are several things you can do. Eg. get at diodeless power J-FET from **broken link removed** , or you could connect two MOSFETs in series to form a bidirectional configuration (see page two in this pdf document **broken link removed** ).

By the way, all MOSFETs have a body diode, it's how thay are made. There aren't any without.

mosfet no body diode

Drain and Source build it on substrate. Substrate and source usualy connect togetter. Therefore all 3 pin MOS have reverse drain source diode.

You must find 4 pin mos if you dont want to reverse diode .
(Not connected source and substate)

pin1 D
pin2 S
pin3 G
pin4 Substrate

In power electronics the way to do not use the parasitic intrinsic MOS diode is to use a diode in series with the MOS, so that the current only flows in one direction.

All Jfets have not body diode.

There are no Jfet for high power and high voltage....

pmos body diode

u can put a forward biased diode in the drain/source

J-FETs don't have a body diode, but lovoltech make some with an added body diode.
