For the extreme case of an unconnected line, the temperature at which clipping begins can be calculated using the data from Figure 9.
To possibly clip, the V
Figure 9 shows that a 0.94 reduction will occur at an ambient temperature of -32 °C. In this example, the TISP3290H3 will allow normal
equipment operation, even on an open-circuit line, provided that the minimum expected ambient temperature does not fall below -32 °C.
To standardize thermal measurements, the EIA (Electronic Industries Alliance) has created the JESD51 standard. Part 2 of the standard
(JESD51-2, 1995) describes the test environment. This is a 0.0283 m
horizontally mounted at the center. Part 3 of the standard (JESD51-3, 1996) defines two test PCBs for surface mount components; one
for packages smaller than 27 mm (1.06 ”) on a side and the other for packages up to 48 mm (1.89 ”). The thermal measurements used
the smaller 76.2 mm x 114.3 mm (3.0 ” x 4.5 ”) PCB. The JESD51-3 PCBs are designed to have low effective thermal conductivity (high
thermal resistance) and represent a worse case condition. The PCBs used in the majority of applications will achieve lower values of
thermal resistance and so can dissipate higher power levels than indicated by the JESD51 values.
