Small-outline transistor

A small outline transistor (SOT) is a small footprint, discrete surface mount transistor commonly used in consumer electronics.

SOT23-3, SOT323, SOT416

The SOT23-3 package is very popular and a common package for transistors, and is also used for diodes and voltage regulators.

SOT89-3

The SOT89-3 electrically only has 3 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 4 leads when looking down at the part.
