Default what schottky have been used?

hello Team!!

Ive read Schottky have the best sound chararistics.

Thinking of using MBR1645 for my dual bridge AX-100

but these are rated at 16A, 45v TO-220AC

Would like to go larger but having problems with the 3 pin schottky Diodes
I can find common cathode but no common Anode to make up a bridge.

IS 16A forward current enough on the MBR1645?
Me thinks it is

Thanks in advance
Dan

Dan,

As far as I know, there is no common-anode 3-pin schottky. To make a two unit full bridge, you will need to use the MUR1620CT and MUR1620CTR (common-cathode and common-anode, respectively). These ultrafast dual-unit rectifiers are made by OnSemi. I have used them in SMPSs for several years now, with good success.

Same types you would find in most car amps with PWM DC-DC converters.

Hope this helps!

Regards,

Steve

Hi,

I´ve used STPS 80H100TV in my Aleph-X. One piece = 2 Schottkys

NP said he is using BYW99W-200 in the XA series.
These are three pin common cathode

Just how do you make a bridge with only common cathode??

This is causing some headache!!
