The MPS6521 is dissipating 2.0 watts peak under the
following conditions:
Using Figure 19 at a pulse width of 1.0 ms and D = 0.2,
the reading of r(t) is 0.22.

Figure 19. At high case or ambient temperatures,
thermal limitations will reduce the power that can be
handled to values less than the limitations imposed by
second breakdown.
