Crydom HS Series Heat Sinks
Thermal Management is of prime importance in the application and
use of Panel Mount Solid State Relays due to their internal power
dissipation of approximately 1 watt/amp of switched load current.
Crydom’s HS Series of heat sinks, designed with “state of the art”
thermal design software, offers optimized thermal performance,
size and cost for a variety of single, dual and three phase Solid State
Relay applications.
S i n k s
Crydom tests are exhaustive, including 100%
verification at final test. After units are completely
assembled, they must pass a complete set of electrical
tests, which are performed twice, once prior to
encapsulation and then again afterward.

Quality Assurance conducts ongoing product reliability
verification tests, gathering precise data on the quality
of our power semiconductor vendors and the silicon
chips they provide. Additional tests are performed to
meet specific customer burn-in requirements.
Heat Sink Selection
A
Why Heat Sinks are required for Reliable Solid
State Relay operation
H e a t
S i n k s
Heat Sinks are required to insure the proper operation and long term
reliability of Solid State Relays because they provide a means to dissipate
the power that is normally developed internally in the SSR into the
surrounding ambient air and maintain a safe operating temperature.
All SSRs in their conduction state create thermal energy in the output
semiconductor at the rate of approximately 1 to 1.5 watts per ampere of load
current for AC output SSRs, and 0.2 to 1.5 watts per ampere of load current
for DC output SSRs depending upon their design. This power dissipation
raises the Solid State Relay’s operating temperature above the surrounding
ambient.
Solid State Relays can operate reliably without heat sinks up to
approximately 5 amps of load current depending upon model, duty cycle
and ambient temperature. Free air ratings of traditional panel mount SSRs
may be as high as 8 to 10 amps, but this rating relies on the SSRs exposed
metal base plate acting as a heat sink, meaning that it must be exposed to
ambient air.
Heat Sinks are made of high thermal conductive material such as
aluminum. Not only is aluminum’s thermal conductivity high, its cost is
relatively low. Although other materials such as steel may provide a limited
measure of heat sinking, thermal conductivity of these materials are
relatively low compared to aluminum and therefore far less effective as a
Heat Sink. Coatings also tend to diminish the thermal dissipation
effectiveness of most materials and except anodizing, should be avoided.
Heat Sink performance is rated by thermal impedance, measured in °C per
watt (°C/W) (thermal impedance is the inverse of thermal conductivity).
Thermal impedance represents the resistance to the transfer of thermal
energy, therefore lower numerical thermal impedance ratings mean more
efficient heat transfer.
Thermal Impedance ratings of Heat Sinks are based upon natural
convection air flow. To achieve this performance, the Heat Sink must be
oriented such that air flow over its finned surface is maximized. Generally
this means the fins should be orientated vertically.
Significant improvement in Heat Sink performance can be achieved by
providing forced air flow over the Heat Sink’s surface area. Fans delivering
relatively small volumes of air can reduce the Heat Sink’s thermal
impedance substantially, thereby improving its efficiency and consequently
the SSRs reliability.
Selecting a Heat Sink for a given Solid State
Relay application
Crydom offers technical assistance selecting a heat sink for any given SSR
application through its Applications Engineering Department and on its web
site. Available “White Papers” and a selection “tool” to calculate a heat sink
rating based upon load current and ambient temperature are available at
www.crydom.com.
How to calculate and select a Heat Sink for a
given Solid State Relay application
The basic structure of a Solid State Relay includes an internal power
semiconductor mounted to an electrical insulator which in turn is mounted
to the Solid State Relay’s base plate. To form an assembly, the SSR with an
accompanying thermal interface material placed on its base plate is then
torque mounted to the Heat Sink.
The thermal model representing the above configuration includes the
following elements:

Solid State Relay - Heat Sink Assembly Thermal Model
To determine the minimum Heat Sink rating (RΘ hs) required for a particular
application, the SSRs internal power dissipation must first be calculated.
The power developed in the SSR will be the product of the actual load
current in amps times the SSRs specified on state voltage drop at that
current ( Pd = If x Vf). Note: Manufacturers generally specify 'maximum
forward voltage drop' in their data sheets. Typical voltage drops are often
much lower.
For this example, assume that a 25 amp AC output SSR is selected to switch
an AC load current of 18 amps with forward voltage drop specified to be 1.25
volts. Therefore the power generated in the SSR is 18 amps times 1.25 volts
= 22.5 watts.
Next, determine the Solid State Relay’s specified thermal impedance and
allowed maximum internal temperature (if the max internal temperature is
not specified by the manufacturer, assume 125 °C as this is a common value
for many AC power semiconductors). For this example, assume RΘ ssr of 0.3
°C/W and Tj of 125 °C.
The next step is to determine the maximum operating ambient temperature
(TA) in °C that the SSR will be expected to operate in its application. The
ambient value should be the ambient air temperature of the local
environment such as the interior of a control cabinet where the SSR and
Heat Sink are to be mounted. In this example, assume TA of 55 °C.
Finally, the thermal impedance of the interface material (RΘ tp) must be
determined. These materials will vary from 0.02 to 0.1 °C per watt
depending upon the type and thickness selected. For this example, assume
that the thermal impedance of the selected interface material RΘ tp is 0.05
°C/W.
The first calculation is to determine the temperature span (∆t) that the
SSRs power must be dissipated into in order to maintain its proper
operation. This will be the difference between the SSRs maximum allowed
internal temperature and the local ambient temperature. ∆t = Tj max – TA.
In this example the result would be: ∆t = 125 – 55 = 70 °C.
The maximum allowed temperature rise noted above, ∆t, must then be less
than or equal to the combined sum of temperature rises across the three
impedances times the power being developed in the SSR. ∆t < (RΘ ssr + RΘ tp
+ RΘ hs) times Pd. For this example it would be 70 < (0.3 + 0.05 + RΘ hs) x 22.5.
Therefore the Heat Sink thermal impedance is RΘ hs < (∆t /Pd) – (RΘ ssr + RΘ tp)
or 70/22.5 – 0.35, equaling 2.76 °C/W.
Therefore in this example, a 2.75 °C/W or larger (lower numerical value)
Heat Sink should be used with the Solid State Relay in the application as
described above.

Why Select a SSR/Heat Sink Assembly versus
a Solid State Relay and a Heat Sink?
Assemblies offer the advantage of eliminating the calculations and heat sink
selection during the design phase of a project, and they eliminate the
assembly process during the production phase of a project. Thermal
derating curves for each SSR/Heat Sink combination make the selection of
the best possible solution significantly easier. The SSRs and Heat Sinks
arrive fully assembled with thermal interface material and mounting screws
torqued to the correct values and are “ready to use”. Optional available DIN
rail mounting brackets can also be ordered pre-installed on the heat sink,
further easing mounting.

Crydom offers technical assistance selecting a SSR/Heat Sink Assembly for
any given SSR application through its Applications Engineering Department
and on its web site. Available “White Papers” and a selection “tool” to
determine the optimum SSR/Heat Sink Assembly for an application based
upon load current & voltage, control voltage and ambient temperature are
available at www.crydom.com/en/HSseries.
How to Select a Solid State Relay/Heat Sink
Assembly from the catalog
3
Each Assembly carries a maximum load current rating verses ambient
temperature, line voltage rating and control voltage rating. There are load
current ratings available up to 80+ amps AC, line voltage ratings available
up to 660 VAC and all models are available with DC control voltage.
Selection of the best assembly can be accomplished as follows:
2
3
4
5
6
7
Determine what maximum line voltage is required for the application.
Determine the input control voltage required or voltage range available.
Determine the maximum load current and maximum ambient
temperature that the Assembly is expected to operate in.
Establish the preferred mounting method, panel or DIN rail.
Once the above information is gathered, examine each Assembly’s
derating chart in the catalog and select models with suitable combined
rating for the required load current at the required ambient temperature.
From this group of Assemblies, select a model with the correct
combination of line voltage, control voltage and required mounting.
Order the Crydom SSR/Heat Sink assembly from your preferred Crydom
Distributor or contact your local Crydom Representative or Regional
Sales Office for more information or technical assistance.
Don’t find the combination of ratings
you need?
Crydom markets a broad selection of class leading Solid State Relays. We
not only offer the customer the ability to select among a wide range of
standard panel mount power SSR products, including AC output or DC
output, random or zero turn on, single, dual or 3 phase SSRs mounted to
any of our available heat sinks, but we can adapt the design of the Solid State
Relay and even the Heat Sinks themselves to precisely meet your
application requirements. Consult your local Crydom Representative for
more information and assistance.
