Small Outline J-leaded package (SOJ) Definition

SOJ stands for "Small Outline J-leaded package".

Small Outline J-leaded package (SOJ) is a J-leaded package with leads coming out of two sides of the package.

Compared to Small Outline Package (SOP), which has a gull wing (L-shaped) lead shape, Small Outline J-leaded package (SOJ), which has a J-shaped lead shape, has the advantage of less lead deformation.

The pin pitch of the Small Outline J-leaded package (SOJ) is 50 mils (1.27mm).

The number after SOJ indicates the number of pins. For example, SOJ8 means a 8-pin SOJ.

Also, the "package material" is changed by adding an English letter in front of SOJ.

Difference between "SOJ" and "QFJ"

The package name changes depending on whether the J-shaped leads exit from two sides or four sides of the package.

Leads coming out of two sides: Small Outline J-leaded package (SOJ)
Leads coming out of four sides: Quad Flat J-leaded package (QFJ)

The following article explains the "Quad Flat J-leaded package (QFJ)" in detail. If you are interested, please check it out from the link below.

Difference between "SOP", "SOJ", and "SON"

The package name changes depending on whether the leads coming out of the two sides of the package are gull wing (L-shaped) leads, J-shaped leads, or electrode pads.

Gull-wing (L-shaped) lead: Small Outline Package (SOP)
J-shaped lead: Small Outline J-leaded package (SOJ)
Electrode pad: Small Outline Non-leaded package (SON)

Types of Small Outline J-leaded package (SOJ)

P-SOJ

The "P-" in front of SOJ stands for "plastic".

Therefore, "Plastic SOJ (P-SOJ)" means a "SOJ whose package material is plastic".

C-SOJ

The "C-" in front of SOJ stands for "ceramic".

Therefore, "Ceramic SOJ (C-SOJ)" means a "SOJ whose package material is ceramic".
