The Aavid Thermalloy line of low profile surface mount
heat sinks are suitable for SMT power semiconductor
devices in D-PAK, D
2
PAK, D
3
PAK and SO-10 packages.
Their unique design removes heat indirectly through
conduction without making contact with the SMT
device like traditional through hole solutions. The semi-
conductor’s conventional copper drain pad is modified to
extend beyond the edges of the semiconductor package
providing space to mount the heat sink. The device and
heat sink are soldered directly to the modified drain pad
creating a thermal transfer path from the package tab
to the surface mount heat sink. In addition, the elevated
"Wings" of the heat sink provide ample surface area to
dissipate the heat into the surrounding environment.
FEATURES AND BENEFITS:
• RoHS compliant 100% matte tin
plating with nickel underplate
• No attachment holes required
in the printed circuit board
• Wing configuration will not
interfere with adjacent components
• Available in tape and reel packaging for use
with automated SMT pick and place equipment
• Compatible with both tin-lead
and lead free (Sn/Ag/Cu) solders

随着阅读器与标签价格的降低和全球市场的扩大，射频标识 RFID(以下简称RFID)的应用与日俱增。标签既可由阅读器供电(无源标签)，也可以由标签的板上电源供电(半有源标签和有源标签)。由于亚微型无源 CMOS 标签的成本降低，库存和其他应用迅速增加。一些评估表明，随着无源标签的价格持续下降，几乎每一个售出产品的内部都将有一个 RFID 标签。由于无源 RFID 标签的重要性及其独特的工程实现...[详细]
