Reference PDF, 38.3 KB, for the 2SB1335 transistor, listed under schematics although it covers a single semiconductor rather than a circuit board. The 2SB prefix in the Japanese JIS system indicates a PNP device for low-frequency service. The name states nothing about manufacturer or package. It is useful for pin identification ahead of diode-mode testing, for reading electrical limits, and for confirming a substitute will tolerate the same voltage, current and heat.
