 Date Published: April 6, 2015 Last Modified: December 24, 2018

## Overview

 Name TO-220F (Transistor Outline 220F) Synonyms TO-220F (JEDEC)SOT-186ATO-220F-3 (as far as I know this package only comes in a 3-pin variant, so the "-3" is redundant) Similar To TO-220ABTO-220AC Mounting Through-hole Pin Count 2 Pitch 2.54mm Solderability Easily soldered by hand, but tab requires a fair amount of power to solder. Thermal Resistance $$T_{JC} = 3^{\circ}{\rm C}/W$$$$T_{JA} = 55^{\circ}{\rm C}/W$$ (component standing vertical on PCB in free, non-moving air) Land Area n/a Height The body is 15.8mm high, and the legs are 14.4mm high. 3D Models n/a Common Uses MOSFET's

## A TO-220 Package With An Insulated Body

One of a disadvantages of the TO-220AB package is that the metal tab, although great for heatsinking reasons, is connected to the middle pin of the component.

The TO-220F is a variant of the TO-220 package which has an insulated metal tab, which is not electrically connected to any of its pins. Some thermal performance is sacrificed because of this insulating layer.
