The 2N/PN/SST4391 series features many of the superiorcharacteristics of JFETs which make it a good choice fordemanding analog switching applications and for specializedamplifier circuits.The 2N series hermetically-sealed TO-206AA (TO-18) can isavailable with processing per MIL-S-19500 (see MilitaryInformation). Both the PN, TO-226AA (TO-92), and SST,TO-236 (SOT-23), series are available in tape-and-reel forautomated assembly (see Packaging Information).
