PDF reference sheet, 214 KB, for the 2N6282 discrete device, listed as a schematic but most likely a datasheet. The RE suffix is not defined anywhere in the name; it may indicate a reissued version. The JEDEC 2N series covers two-junction parts, mostly transistors. Repair work uses such a file to identify base, collector and emitter or equivalent pins, read breakdown voltages and dissipation limits, and confirm that a proposed replacement fits. Compare the case outline with the part on your PCB before ordering.
