AC input models can becontrolled from a wide range of AC signal sources (90-280 VAC}, and are available in Form A (normally open) configuration only. DC input versions will operate from IC logic signals, and are available in either Form A (SPST, normally open) or Form B (SPST, normally closed} output configurations. _.

It is essential that the user provide adequate heat sinking for the application. The simplified thermal model (figure 1) indicates the basic elements to be considered in the thermal design. The values to be chosen or determined by the user are the case-to-heatsink interface thermal resistance (Recs) and the heatsink-to-ambient thermal resistance (Rysa)- Referring to figures 4 thru 6, the left halves show power dissipation versus load current. The right halves are families of curves which are used in selecting the required heatsink to maintain a maximum case temperature for a given ambient. it is important to note that the thermal resistance values (C/W) shown include both case-to- heatsink interface (Recs) as well as the heatsink- to-ambient thermal resistance (Rusa). Thus, when selecting a heatsink, the value of A must be subtracted from the number indicated by the curve in order to determine the required heatsink- to-ambient thermal resistance (R gsa). As a point of information, if the SSR is firmly mounted on a smooth heatsink surface using thermally conductive grease, the value of Regs (case-to-heatsink interface) will typically be 0.1C/W or less. Examples of how the curves are used are explained below in conjunction with figure 3. Example 1. {fa TD1225 is mounted on a heatsink with a thermal resistance of 1C/W (including Recs) and must operate in an ambient of 60C, the allowable current of 18A may be determined by following the route A,B,C,D. Additional information of power dissipation and maximum allowable case temperature can be found by extending line C,B to points E and F where the values of 19Wand 81C are read. Example 2. If a current of 14A is required in an ambient of 50C, the necessary heatsink, plus interface, thermal resistance of 2.7C/W may be determined by following the route G,H,I,J. Additional information of power dissipation and case temperature can be found by extending line H,J to points L and K where the values of 14W and 87C are read. This information can be used in heatsink selection from manufacturer's dissipation versus thermal resistance curves such as those shown in figure 2. The thermal resistance of curve (a) at 14 watts is 2.5 CMW. This is better than the required 2.7 CAW in example 2, allowing 0.2C/W for Rgcs, and is therefore suitable for this application. Alternatively, heatsink (b) at 14 watts is 1.9C/W. Adding 0.1C/W for Rgcs and returning to figure 3, it would allow operation at a maximum ambient of 58C instead of 50C. Confirmation of proper heatsink selection can be achieved by actual temperature measurement under worst case conditions. The measurement can be taken on the metal baseplate in the area of the mounting screw, and should not exceed the maximum allowable case temperature shown in graphs. Surge Characteristics The curves in figures 7, 8 and 9 apply to a non- repetitive uniform amplitude surge of a given time and peak current, preceded and followed by any rated load condition. Also shown is the number of these surge occurrences that can be tolerated before device damage. For example, a life of 10 surge occurrences can be estimated for a 25 amp peak surge (figure 8) of 0.1 seconds duration. The junction temperature must be allowed to return to its steady-state value before reapplication of surge current. Control of conduction may be momentarily fost if currents exceed the 10 curve values from initial junction temperatures greater tnan 40C. ao No Heatsink Ow - Ow -E Output Rex Rreca Semiconductor (Junction oem Heat Flow Temperature} With Heatsink Cw) -ww-C) THERMAL RESISTANCE: Ambient (Air Temperature) Oe Rocs t Rosa t Heatsink Temperature Rex = Junction to Case Case Temperature To- Ta = Pp (Raca) THERMAL RESISTANCE (Ry. c/wi od Reca = Case to Ambient = Po (Rags * Rusa) Racs = Case to Sink Where Py = Power 1.
