The diagram of fig. 2 shows the maximum dissipated power Ptot and the RQJA as a function of the side Òl Ó of two equal square copper areas having a thickness of 35µ (see fig. 1). In addition, it is possible to use an external heatsink (see fig. 3). During soldering the pins temperature must not exceed 260ûC and the soldering time must not be longer than 12 seconds. The external heatsink or printed circuit copper area must be connected to electrical ground. Mounting Instructions Figure 2 - Max.
