PDF reference sheet for the 2N5320 transistor, 45.0 KB, sitting alongside the 2N5322 document in the index. No vendor or revision is named. Expect absolute maximum ratings, DC gain figures, saturation voltages and the mechanical drawing showing which lead is emitter, base and collector. Repair work uses this data to verify a suspect part with a diode test, decide whether a modern equivalent is suitable, and check heat dissipation limits. Match the package on the board with the outline before ordering a replacement.
