Engineering:Small-outline transistor

From HandWiki
Short description: Family of discrete surface mount transistors
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]

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.
