I'm trying to find a replacement part for this component. My knowledge of electronics is rudimentary at best and I'm struggling to find this component just by the text.

It looks like ST D1N B60 C027, but I can't find a replacement online.

It looks like it is an STMicroelectronics STD1NB60 n-channel, 600 V, 1 A MOSFET with an RDS(on) of about 8 Ω.

Supplier sites say this STD1NB60 is obsolete, but if you can't buy one anymore you should be able to find one with similar specs; maybe the STD1NK60 is a direct replacement (I haven't checked).

It's a STD1NB60 N-channel 600V 1A PowerMesh MOSFET, made by STMicroelectronics.
