SOJ - Small Outline J-Lead Package

The 'Small Outline J-Lead Package', or SOJ, is a small rectangular surface-mount plastic-molded integrated circuit package with J-formed leads. The leads protrude from the longer edge of the package. The SOJ is also sometimes referred to as 'SOIJ', or J-leaded small outline IC package.

SOJ packages are JEDEC-compliant and come in a variety of body widths, the most popular of which are 7.5 mm (300 mils) and 10.2 mm (400 mils). The standard SOJ lead pitch is nominally 50 mils (1.27 mm). The SOJ may be shipped in tubes or tape and reel.

A similar package outline that has gull wing leads instead of J-shaped leads is known as the SOIC.
