A 39.8 KB PDF filed under schematics that covers the 2SB835 transistor, with an _E suffix in the name whose meaning is not stated and may simply denote an edition or source. Under JIS numbering the 2SB prefix identifies a low-frequency PNP device. When a board fails, a sheet like this lets you confirm the base, collector and emitter order, the package style and the limit values, so a replacement from another maker can be checked against the original before it is soldered in.
