Datasheet PDF for the 2SB1020A, 216 KB, filed in the schematic category. Under Japanese JIS designation 2SB means a PNP transistor intended for low-frequency circuits, and the A suffix normally signals a revised variant that may have different ratings from the plain type. The sheet should detail maximum voltage and current, power dissipation, gain and package. Confirm the full part number including the suffix on the device, and check the pinout against the PCB before installing a replacement.
