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

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
