PO = (VO) x (IO) = 5 x 20 = 100 W
Although the two examples above use 100 ° C
as the maximum case temperature, for
extremely high reliability applications, one may
design to a lower case temperature as shown in
Example 4 on page 35.
Heat Sink Configuration
Several standard heat sinks are available for
the AEH 24Vin 50 W to 150 W modules as
shown in Figure 33 to Figure 35.
The heat sinks mount to the top surface of the
module with screws torqued to 0.56 N-m (5 in.-
lb). A thermally conductive dry pad or thermal
grease is placed between the case and the
heat sink to minimize contact resistance (typi-
cally 0.1° C/W to 0.3° C/W) and temperature dif-
ferential.
Nomenclature for heat sink configurations is as
follows:
WDxyyy40
where:
x = fin orientation: longitudinal (L) or trans
verse (T)
yyy = heat sink height (in 100ths of inch)
For example, WDT5040 is a heat sink that is
transverse mounted (see Figure 35) for a 61
mm x 57.9 mm (2.4 in.x 2.28 in.) module with a
heat sink height of 0.5 in.
Heatsink Mounting Advice
A crucial part of the thermal design strategy is
the thermal interface between the baseplate of
the module and the heatsink. Inadequate mea-
sures taken here will quickly negate any other
attempts to control the baseplate temperature.
For example, using a conventional dry insulator
can result in a case-heatsink thermal imped-
ance of >0.5° C/W, while use one of the rec-
ommended interface methods (silicon grease
