A compact 50.1 KB PDF named 1SS375, indexed under schematics but almost certainly a data sheet for one component. JIS numbering assigns the 1SS prefix to small-signal silicon diodes. When a technician finds a damaged diode in a signal or protection path, a sheet like this supplies forward voltage, reverse voltage, current limits and the outline needed to pick a correct substitute. It opens in any PDF viewer. Confirm the polarity marking and package of the original part before relying on these figures.
