## 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. 

I = RMS value of load or SSR 2 TTRMS12 = Time current is on = Time current is off IRMS = (IONT1 )+ T x T2 1 ION = RMS value of load current during on period

## Solenoid Valve and Contactor Loads 

## Transformer 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.

## Control Current Calculation 

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. 

The DC control voltage range is 3–32 VDC. To calculate the control current for any voltage within the 3–32 VDC range, use the formula:

## Applications

## 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 

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. 

|**120 Volt Lamps**|**120 Volt Lamps**|
|---|---|
|SSR CURRENT RATING|LAMP RATING|
|2-Amp|100 Watt|
|4-Amp|400 Watt|
|10-Amp|1 Kilowatt|
|25-Amp|2 Kilowatt|
|45-Amp|3 Kilowatt|
|**240 Volt Rating**||
|SSR CURRENT RATING|LAMP RATING|
|2-Amp|200 Watt|
|4-Amp|800 Watt|
|10-Amp|2 Kilowatt|
|25-Amp|4 Kilowatt|
|45-Amp|6 Kilowatt|



## Heater Loads 

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. 

The following table is a guide to selecting the proper SSR for a given heater load. 

|**Nominal SSR**<br>**Current Rating**|**Maximum**<br>**Recommended**<br>**Heater Current**|
|---|---|
|2-Amp|1½-Amp|
|4-Amp|2½-Amp|
|10-Amp|7½-Amp|

|45-Amp|35-Amp|
|10 480V|8-Amp|
|10 480V|8-Amp|

## 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. 

1.4 EAC CALCULATE RL as:   RL = 10 x SSR full load rating EXAMPLE: 10 amp SSR 120 V AC Line 1.4 x 120 RL = = 1.7 ohm 10 x 10 

The resistors are unnecessary if the control circuit is designed to ensure one SSR is off before the other SSR is on.

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 following table as a guide to the proper selection of an SSR for this application.
