Heat Sinks THERMAL MANAGEMENT FOR SSR' s A major consideration in the use of Solid-State Relays is the thermal design. It is essential that the user provide adequate heat sinking for the application. Crydom heat sinks are designed for excellent thermal management when used with Crydom's Series 1 type package of SSR's and Controllers. 2.06 (52.3) THERMAL RESISTANCE (RsaC/W) HS-1, HS-2 HEAT SINK CHARACTERISTICS 3.0 .689 TYP. (17.5) .689 TYP. (4.8) Correct installation is important to assure heat is dissipated correctly. The Crydom SSR should be firmly (20 in-lbs.) mounted on a clean, smooth heat sink surface using thermally conductive grease. 4.12 (104.6) 2.75 (69.8) 1.60 (40.6) 8-32 THREADED HOLE (2 PLACES) HS-1 2.5 HS-2 2.0 1.875 (47.6) 3.00 TYP.
