This is apparently a "solid state fuse", which is listed as IC401 in the power supply of a Nakamichi SR 4A. I have voltage at D403 which is on the input side of the ICP, but not at D404 which is the output side, so I believe the fuse has blown.
Circuit is attached.
What would be a good replacement for this?
There is also a second one IC402, which is an ICP N15
Thanks

Sorry I can't help with what is a replacement but since I also have an SR-4A I was hoping you had the rest of the schematic also. 🙂
ICP-N5 - Fuse semiconductor ultra-rapid PCB 50V 0.25A | Fuse semiconductor ultra-rapid PCB 50V 0.25A | TME - Electronic components (WFS)
ICP-N5 is rated 250mA, you could sub a piece of fusewire from a standard glass fuse.
Max.
thanks-I have found some data on pico fuses, which seem a good substitute, if it is a single use device?
Is the ICP N5 single use, in that once it has blown it can not be reset or am I missing something here?
and my assumption is that as space was at a premium, that is why it was used?

I believe those solid state fuses are way faster than glass fuses and one time use only.
You have to replace them.

thanks to all- B&D Dent have some- so I have installed and am now onto the next problem with this unit- no display
