Hi, trying to identify a component marked NSD618 in a TO-220 case. Its marked NSD618 B2045G ON AKA. Its at the front end of a Hantek PSU. The ON is in a circle and I think its means ON Semiconductors...but searching their website found nothing. Can anyone help with a datasheet - not least to work out a replacement if its needed.

It may be an in-house number, so there wouldn't be any datasheet for it.

Can you post pictures of the PSU?, and exactly what is wrong with it?.

Also, what model is the scope?.

Disregard the first line--(convoluted device/DOM codes)
MBR2045CTG
ON= Onsemi.
AKA=Polarity

Still no pictures, so we've no idea where it might be in the circuit, or even what's wrong - however, it looks like a secondary rectifier.
