PDF datasheet for the 2N3393, 296 KB, placed in the schematic category. The same size appears for the 2N3390, 2N3391A and 2N3392 entries, which points to one combined family sheet, though only 2N3393 is named here. It contains characteristics, ratings and the case drawing for these 2N-series transistors. Useful for confirming which lead is which and whether a substitute fits the circuit. Open in any PDF reader and read the 2N3393 row of the tables.
