A 209 KB PDF for the 2N6055, carrying an unexplained RE suffix that may indicate a revised edition. It is filed as a schematic but is most likely the manufacturer datasheet for this JEDEC-registered part. The 2N prefix marks a device with two junctions, mostly bipolar transistors. Technicians use the document to verify pinout and case style, look up breakdown voltages and power dissipation, and check test conditions when a measured value looks wrong.
