help! 12v 5A AC to DC circuit

[baskar007]

Hi to all i am new bie to electro tech online.
my name is baskar and live in india.

I have a idea to build amp for my room using TDA1554 chip, I have a data sheet for chip. But i get confused with power supply for this chip, It's require 12v 5A at full volume. i have 12volt 5A transformer but i need AC to DC converter circuit.

If i use bridge diodes which diode can i use for this rating 12Volt 5AMP ?

If you can find one there easily, a "CB radio power supply" will be ideal.

Any way to convert AC to DC !

Thank for this idea, But i already have a transformer which out put is 12 volt 5amp but AC, So i need to convert it to DC how can i do it?.

If i can possible by diodes, Which diode is suitable for 5 amp 12v.
Or is there is other way's to convert ac to dc for my case?

Thanks in advance..

why not try out a normal rectifer circuit using 78XX ICs

The LM7812 is only rated for 1A.

You'll need a booster transistor on a huge heatsink for 5A.

If you insist on using discrete diodes to do your rectification, you could use 4 of these: 10A01-T made by Diodes Inc.

Available from Digikey:

Digi-Key - 10A01CT-ND (Diodes Inc - 10A01-T)

They're only 90 cents each and through hole. They'll handle upto 10A and upto 50V, so they'll work for 5A at 12V.

how about 1N5401 diodes

is can i use 1N5401 diodes(3 amp,50 volt). which value of capacitor i need to be add for filtering? i have a idea to use 2200µf is this rite??

why not try out a normal rectifer circuit using 78XX ICs

how can i use 78XX series with normal diodes mean like 1N4007?

these diodes are capable for only 1 amp. i need at least 3amp current.

I thought you needed 5A?

You mentioned the 1N5401 above which is a 3A diode.

Anyway Google for 5A diode and you get lots of results.
