DESCRIPTION
The J/SSTJ210 Series n-channel JFETs are general-purpose and high-frequency amplifiers for a wide range of applications. These devices feature low leakage (IGSS < 100 pA). capability. The J/SSTJ210 Series is available in tape-and-reel for automated assembly (see Packaging Information).
The TO-226AA (TO-92) plastic package, provides low cost while the TO-236 (SOT-23) package provides surface-mount
For similar dual products, see the 2N5911/5912 and U440/441 data sheets.
