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.
