Wide extruded heat sink with
unequal channel widths on front
and back can accommodate a TO-220,
TO-218, or TO-247 device. Includes two
solderable mounting pins which permit
vertical mounting and eliminate stress
on device leads. Available in three heights.
Versions without hole use clip 6801 (sold
separately) to attach device. See page 97
for clip information.
