Don't want to get into the valve/silicon, which is best, debate. You makes
yer choices and that's OK by me. It's all down to the schematic and what
you believe in....

I use silicon. Don't need a heater and low voltage drop...... IN4007 ? ..
keep seeing it on schematics .... what's wrong with BY127 ? ....seems to
have a better spec.. or .. I now use encapsulated industrial bridges....
About 1" square. Bolt down solid to the chassis with a 1/4" nut and bolt,
have four Lucar/spade connectors.... cost about £2 and are rated at 1500
PIV at 35 AMPS !!!

They don't get very warm with 500mA through them , so a heat sink is not an
issue !!

Any comments ?

Kind regards
jim

HI Jim
Where can you buy the Bridges?
Thanks Phil

Hi, Philip,
Depends where you are in the world, I suppose. The ones I use are made by
either General Rectifier or International Semiconductor bought from RS
Components in Corby, Northamptonshire. They have a huge range of
encapsulated bridges from 1A to 35A with solder or dry connections. and
PIVs up to 1600V I like the single bolt fixing ones 'cause they're simple
to mount and the spade connections avoid any danger of heat damage when
wiring them up
RS are at http://rswww.com

kind regards
jim

go for the gusto and get some silicon carbide high voltage schottky diodes.

no switching noise in the first place!

Are they available to mortals yet? Got a link?

cheers, Ian
