AMZ	Re: Mosfet Splatting >>I use a germanium diode purposely to keep the threshold as low as possible. I measured a Vf on mine of around 1.4V. What mosfet are you using? BS170? I'm preparing some curves for a new diode clipping article and I'll look this one over. As I mentioned in my answer to Aron, and you confirmed, the additional diode can be used to steer the current through the diode of choice. Gate must be connected to the drain to activate the normal diode. BTW, a 1N5819 Schottky has a much lower Vf than a Ge diode. I have several that I got from Mouser but they are commonly available. regards, Jack

As I mentioned in my answer to Aron, and you confirmed, the additional diode can be used to steer the current through the diode of choice. Gate must be connected to the drain to activate the *normal* diode.
