BY224 cross ref

[psycho]

Hi all,
I need to replace the bridge rectifier in an amp and I can't find a cross ref for it. It's a Philips BY224 - all I found was 4.8A/220V DO-4 pkg. Anyone know of a substitute?

Thanks,
Kevin

Greetings Kevin,

That's an old device, but you can easily replace it
with either four diodes or a similar bridge, which will
require that you fashion connecting wires unless you
find an exact physical match.

The easy solution is to use four separate diodes,
like these.

Here's a suitable bridge (may not be physically
the same)

Here's the datasheet. The part number you have is
incomplete, you need to add the PIV rating to the
part number. (Try BY224-600).

If this part is defective there are probably other parts
that caused it to fail. Either do some more testing or
buy more than one replacement...

Comments Welcome!

Hiya bigglez,

Oh, I know there are more components blown. It's in the SMPS for an amp that I inadvertantly pumped 220 into ... I have to crawl through every component and see if they are good or bad. The PWM ctrlr I will replace, along w/ 2 2n4401's and the fuse, MOV, blah blah blah... Lost a few traces, too.

If your interested, its a Gallien-Krueger 2100CEL Guitar amp. circa 1988
