I am looking for high current fast bridge diode to modify +- 125v Switching mode PS. My SMPS -early 80's product-uses CA3524 and 20khz frequency. It is annoying to hear that transformer hum. I want to increase its current 20khz to 40khz or so into inaudible frequency. To do that, I need to replace 3 bridge diodes ( 60, 80 & 120V). I could not find any high current fast bridge diodes on Mouser.com or Digikey.com. Thanks for your info.
Do you have to use a single piece bridge, or do you have room to make one out of discrete diodes?
What is the current rating you need?
What is the current rating you need?
Half bridge, yes. Lot's found in TO-220 case. Full bridge not so much, because extra HF transformer windings come easy and have less loss than another two diodes.
I need a full bridge because I do not have any room for discretes. I need 15A or higher.
If I can not find full bridge, I will settle down with half ones.
Thank you all for replys
