Compare the value found in the load current versus temperature chart with the standard heatsink values and select the heatsink with the next lower value.
## **A lications pp**
This relay is designed for use in applications in which it is exposed to high surge conditions. Care must be taken to ensure proper heatsinking when the relay is to be used at high sustained currents. Adequate electrical connection between relay terminals and cable must be ensured.
**Thermal characteristics** The thermal design of Solid State Relays is very important.
It is essential that the user makes sure that cooling is adequate and that the maximum junction temperature of the relay is not exceeded.
If the heatsink is placed in a small closed room, control panel or the like, the power dissipation can cause the ambient temperature to rise. The heatsink is to be calculated on the basis of the ambient temperature and the increase in temperature.
