Fairchild 1F30SD data sheet
(1/1)
IconicPCB:
Looking fo a data sheet or any information at all on a Fairchild 1f30sd.

Tried google... no joy any references to 1f30sd point to distributors of old and obsolete gear with offers of data sheet upon request... however i do not need to purchase materials.. am trying to understand what the component is.

ON semiconductors, the new owners of Fairchild , are as useful  int his regard as the tits on a bull.
amyk:
Could you post a picture?

IconicPCB:
Certainly... it is the SMD component located between two ferrite core transformers on either side , a blue electrolytic capacitor and axial power resitor in the right half of the image.
amyk:
SMD markings contain date/batch codes too, so you are unlikely to get results by searching for the full mark.
SiliconWizard:
Yeah, no datasheet to be found... and yes I doubt any of those brokers will send you a datasheet unless you place an order (and I'm not even sure they really have one for this).

I'm just guessing that it's probably a diode (single or dual). You could try and confirm this with some simple testing.
