Overview
In 1974, Opto 22 introduced the first liquid epoxy-filled
line of power solid-state relays (SSR). This innovation in
SSR design greatly improved the reliability and reduced the
cost of manufacturing. At that time, we also incorporated
into our manufacturing process 100% testing of every relay
produced under full load conditions. By 1978, Opto 22 had
gained such a reputation for reliability that we were recognized
as the world’s leading manufacturer of solid-state relays. Through
continuous manufacturing improvements and the same 100%
testing policy established 22 years ago, Opto 22 is still recognized
today for the very high quality and reliability of its complete line
of solid-state relays.

Heat Sink Calculation
Like all semiconductor devices, SSR current
ratings must be based on maximum junction
temperature. All Opto 22 SSRs operate
conservatively at maximum junction temperatures
of 110° C. Determining an adequate heat sink
for a given SSR conducting a given current is
very simple.
Note: Thermally conductive grease must be used
between the relay base and the heat sink.
Sample Calculation Given:
120-Volt, 20-Amp Load
50° C Ambient Air
Choose Model 120D25 SSR.
Calculate dissipation as: 20 amps x 1.3 Watts per amp = 26 Watts
Calculate temperature rise junction to SSR base as: 26 Watts x 1.2° C per Watt = 31.2° C
Calculate allowable temperature of heat sink by subtracting 31.2° C from 110° C allowable junction temperature:
110° C-31.2 = 78.8° C
The heat sink is in a 50°C ambient, therefore, allowable temperature rise on heat sink is: 78.8° C-50° C = 28.8° C
If heat sink is allowed to rise 28.8° C above ambient, then the thermal resistance of the heat sink is simply the 28.8° C rise divided by the 26
Watt. Any heat sink having a thermal resistance less than 1.1° C per Watt will be adequate.
Duty Cycle Calculation
When solid-state relays are operated in an on/off mode, it may be advantageous to calculate the RMS value of the current through the SSR
for heat sinking or determining the proper current rating of the SSR for the given application.
IRMS = RMS value of load or SSR
T1 = Time current is on
T2 = Time current is off
ION = RMS value of load current during on period

IRMS =
(ION) x T1

Transformer Loads
Solenoid Valve and Contactor Loads
Careful consideration should be given to the selection
of the proper SSR for driving a given transformer. Transformers
are driven from positive saturation of the iron core to negative
saturation of the core each ½ cycle of the alternating
voltage. Large inrush currents can occur during the first ½ cycle
of line voltage when a zero voltage SSR happens to turn on
during the positive ½ cycle of voltage when the core is
already in positive saturation. Inrush currents greater than
10 times rated transformer current can easily occur.
The following table provides a guide for selecting the
proper SSR for a given transformer rating.
All Opto 22 SSRs are designed to drive inductive loads such as solenoid
valves and electromechanical contactors. The built-in snubber in each SSR
assures proper operation into inductive loads. The following table is a
guide in selecting an SSR to drive a solenoid or contactor.

All Opto 22 DC controlled SSRs have a control circuit consisting of 1000 ohms in
series with an LED. Since 3 volts is required to turn on any SSR, the maximum current
required is (3 volt - 1 volt) divided by 1000 ohms which equals 2.0 mA. The 1 volt is subtracted
from the 3 volt signal because 1 volt is dropped across the LED. For higher control voltages,
an external resistor can be added in series with the control voltage to limit the control
current. To limit the control current to 2 mA, calculate the external resistor RC = 500 (EC- 3)
where EC = the control voltage.

Solid-State Relays In Series
In applications requiring greater current rating at higher voltage,
two Opto 22 SSRs may be operated in series for double the
voltage rating. The built-in snubber in each SSR assures proper
voltage sharing of the two SSRs in series. In the diagram below,
two 240-volt, 45-amp SSRs are connected in series for operation
on a 480-volt line. The control is shown with a parallel hook-up
but it should be noted that a serial connection can also be
implemented.
Lamp Loads
Heater Loads
Since all Opto 22 SSRs are zero voltage switching, they
are ideal for driving incandescent lamps because the
initial inrush current into a cold filament is reduced.
The life of the lamp is increased when switched by a
zero voltage turn on SSR. The following table is a guide
to selecting an Opto 22 SSR for switching a given
incandescent lamp.
Care should be taken in selecting a SSR for driving a heater load if
the load is cycled on and off in a continuous manner as might occur in
a temperature control application. Constant cycling can cause thermal
fatigue in the thyristor chip at the point where the chip bonds to the
lead frame. Opto 22 employs a thick copper lead frame for mounting
the SCR chips in the power series SSRs to eliminate thermal fatigue
failures. In addition, Opto 22 recommends operating any SSR at 75%
rated current for cycling heater loads to ensure complete reliability.

Single-Phase Reversing Motor Control
The circuit diagram illustrates a typical 1 Ø motor winding inductance and the phase shift
capacitor can cause twice line voltage to appear across the open SSR. A 240-volt SSR should be
used for a 120-Volt line. During the transition period when one SSR is turned on and the other
SSR is going off, both SSRs may be on. In this case, the capacitor may discharge through the
two SSRs, causing large currents to flow, which may destroy the SSRs. The addition of RL as
shown will protect the SSRs from the short circuit capacitor discharge current.
CALCULATE RL as: RL =
1.4 EAC
10 x SSR full load rating
The resistors are unnecessary if the
control circuit is designed to ensure
one SSR is off before the other SSR is
on.

Three-Phase Motor Control
Three-phase motors may
be controlled by solid-state
relays as shown. A third
SSR as shown is optional,
but not necessary. The
control windings may be
connected in series or
parallel. Care should be
taken to ensure that surge
current drawn by the motor
does not exceed surge
current rating of the SSR.

Three-phase reversing motor control can be implemented with four
SSRs as shown in the connection diagram. The SSRs work in pairs
with SSR1 and SSR3 operated for rotation in one direction and SSR2
and SSR4 operated for rotation in the reverse direction. The
resistor R1 as shown in the connection diagram protects against
line-to-line shorts if SSR1 and SSR4 or SSR3 and SSR2 are on at
the same time during the reversing transition period. Use the
