Hello. What diode replacement for SB3A0 works in the Tv FUnai power supply. Could BY228 be.

Hello, as the SB3A0 datasheet says it is a 3A / 100V Schottky diode. BY228 should be OK, it has a bit weaker current impulse resistance 50A vs 80A, it may be important depending on where it is placed. With Vishaya, maybe the EGPxx series depends on where it is located in the system. greetings

SB3A0 This is a low Uf Schottky diode while the BY228 is a regular high Uf up to 1.5V silicon diode. Possibly SR310

Thank you for your help, I used the SR310 diode.
