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.
