Reference PDF of 42.8 KB for the 2SB956 semiconductor, marked with an _E suffix whose meaning the name does not give. The 2SB prefix follows the Japanese JIS scheme for low-frequency PNP transistors. Expect the usual data sheet content: absolute maximum ratings, hFE ranges, saturation voltages and a package drawing with the lead order. Before swapping a failed device, compare its case and pinout with the drawing here, because similar-looking packages can carry a different lead order.
