DESCRIPTION
The 2N/PN/SST4391 series features many of the superior
characteristics of JFETs which make it a good choice for
demanding analog switching applications and for specialized
amplifier circuits.
The 2N series hermetically-sealed TO-206AA (TO-18) can is
available with processing per MIL-S-19500 (see Military
Information). Both the PN, TO-226AA (TO-92), and SST,
TO-236 (SOT-23), series are available in tape-and-reel for
automated assembly (see Packaging Information). For similar
dual products, see the 2N5564/5565/5566 data sheet.
