PAD5 Trr

GK · 20th February 2009, 04:42 AM

Any semiconductor experts here willing to take an educated guess at what the Trr of the PAD5 diode is?

Stupid datasheet doesn't specify if

Glen -- I looked at my old Siliconix data book - not there either. But its capacitance is LEQ that of a 1N914. So maybe trr is equivalent - maybe a couple nanoseconds depending on circuit????

Of course, that can be lowered with judicious application of the Mexican dinner tweak

You might want to upgrade your avatar. Have you seen the news on Sheyla Hershey?

OK, thanks. A ns or two (or maybe three) is what I'm after. I've got a few of these PAD5's laying around somewhere. Think I'll just have to measure them. Might have some taco's in the fridge too. Hmmmm......

Cheers,
Glen
