Heatsink sizing is one of the most critical steps when using solid state relays (SSRs). The heatsink provides the necessary thermal dissipation for the power losses in the SSR power unit. This paper gives a detailed thermal analysis of the SSR and heatsink and proposes ways how OEMs can:
-Savespace in the electrical cabinet -Increasethe load current in the SSR -Saveon overall system cost
