DESCRIPTION
The J/SST201 series features low leakage, very low noise,
and low cutoff voltage for use with low-level power supplies.
The J/SST201 is excellent for battery powered equipment and
low current amplifiers.
The J series, TO-226 (TO-92) plastic package, provides low
cost, while the SST series, TO-236 (SOT-23) package,
provides surface-mount capability. Both the J and SST series
are available in tape-and-reel for automated assembly (see
Packaging Information).
For similar products in TO-206AA (TO-18) packaging, see the
2N4338/4339/4340/4341 data sheet.
For applications information see AN102 and AN106.
