Concise 41.8 KB PDF for the 2SD958, named with an _E suffix of unstated meaning and filed among schematics. Under Japanese JIS designations, 2SD denotes an NPN transistor for low-frequency applications, so the content is a component specification rather than a circuit diagram. Repairers consult it to confirm pin layout before in-circuit diode testing, to check collector voltage and current ceilings, and to qualify a substitute with matching polarity, package and equal or higher ratings.
