Filed under schematics, this compact 39.7 KB PDF is named after the 2SB976 part number, a Japanese JIS-style designation where the 2SB prefix marks a PNP transistor intended mainly for low-frequency work. The _E suffix is a revision or edition marker that the name does not explain. A sheet like this normally gives pinout, package outline, maximum ratings and electrical characteristics. Use it to confirm the pin order and voltage and current limits before fitting a replacement, and compare the marking on the part you remove.
