Reference PDF for the BD136, BD138 and BD140 transistor series, catalogued as a schematic but in practice a component datasheet of 51.2 KB. Expect pinout, package outline and a table of ratings that separates the three variants mainly by voltage class. These parts are widely used as complementary partners to the BD135, BD137 and BD139 in amplifier and driver circuits. Use the document to confirm lead order before fitting a replacement and to pick the variant whose voltage rating meets or exceeds the original in the circuit being repaired.
