PDF of 169 KB for the 2SB1016A transistor, listed under schematics. JIS numbering uses 2SB for PNP transistors designed for low-frequency service, and the trailing A generally indicates a revised model rather than the original 2SB1016. Expect a package drawing, pin assignment and full electrical characteristics. When replacing a failed unit, match polarity and package, check that ratings are equal or higher, and inspect mounting and heatsinking if the device dissipates significant power in the circuit.
