BOARD LEVEL POWER SEMICONDUCTOR HEAT SINKS
These exceptionally low-cost heat sinks can be mounted horizontally under a TO-220 or
TO-202 case style with a maximum height of only 0.375 in. (9.4). For added performance,
a 271 Series heat sink can also be used for double-sided heat dissipation.

The 270-AB and 280-AB accept one power semiconductor; the 272-AB is designed for two
power semiconductors. Specify solderable tab options for the 272 Series by the addition of
suffix “O1” or “02” to the standard part number (i.e. 272-AB01 or 272-AB02).
