PDF datasheet for the 2N5457 N-channel JFET, 111 KB, filed under schematics. The RE suffix in the name is not explained and may mark a reissued or alternate vendor copy, so treat it as unconfirmed. Inside you can expect pin assignments, absolute maximum ratings and IDSS and cutoff voltage ranges. These figures matter when matching a replacement in audio preamps, buffers or switching stages. JFET parameters spread widely even within one part number, so measure or select parts where the circuit is sensitive.
