Small-outline transistor

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

Package configurations

Two of the most common package configurations are the SOT-23^[1] and SC-70.^[2] Other package configurations are SOT-66, SOT-89, SOT-143, SOT-223 and TSOT-23, which is a thinner version.^{[citation needed]} This package is used for transistors, comparators, diodes and other simple components. There are several examples of varying types in tables below. Dimensions are used for orientation, for exact information (and footprint) is neccesary to find apropriate outline drawing.
