DESCRIPTION

The J/SST270 series consists of all-purpose amplifiers for

designs requiring p-channel operation.

The TO-226AA (TO-92) plastic package provides a low-cost

option, while the 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).
