Small-outline transistor

Size comparison of transistor packages. Two surface-mount packages, SOT23 and SOT223, are shown next to through-hole packages

A small outline transistor (SOT) is a family of small footprint, discrete surface mount transistor commonly used in consumer electronics. The most common SOT are SOT23 variations,[1]. SOT23-5 differs from SOT23 in a wider body of 1.6 mm (0.063 in) instead of 1.3 mm (0.051 in). Also, manufacturers offer the nearly identical thin small outline transistor (TSOT/TSOP) package, where lower height is important.[2][3] [4][5]

SOT23, SOT323, SOT416

The SOT23 package is very popular and a common package for transistors, as well as diodes and voltage regulators.[1]

SOT23-5, SOT353, SOT553

SOT23-6, SOT363, SOT563

SOT23-8

SOT54

SOT54 is an alternate designation for the JEDEC TO-92 package.[28]

SOT23-4, SOT143, SOT343

SOT490

SOT89-3

The SOT89-3 electrically only has three leads (contact/pin). The wide lead (tab) is physically part of the middle lead on the other side of the package. Some call this package a SOT89-4, since it visually appears to have four leads when looking down at the part.

SOT89-5

The SOT89-5 electrically only has five leads (contact/pin). The middle lead is physically part of the middle lead on the other side of the package. Some call this package a SOT89-6, since it visually appears to have six leads when looking down at the part.

SOT223 (SOT223-4)

The SOT223-4 package is a popular package for voltage regulators. It was introduced by Philips.[32]

SOT223-5

The SOT223-5 package is a popular package for voltage regulators.

SOT223-8

The SOT223-8 package is a popular package for bridged quad transistors.
