NSD618 datsheet - Hantek oscilloscope power supply

[punkieys17]

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?.

A clue ? "NSD" a On Semi diode nomenclature.....600V maybe.....?

Post a question at On Semi support.....


Regards, Dana.

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.
