Power dissipation is 2.8 W at an ambient temperature of 25 ˚C when mounted on a
double-sided copper board using FR4 standard, 70 µm of copper, 39 x 30 x 1.6 mm.
The energy absorbed by the resistor expressed in Joules can be calculated by
multiplying the peak power of the pulse in watts times the length of the pulse in
seconds.
The energy should not exceed the limits shown in the graph. The overload voltage
should not exceed 1.5 times the maximum operating voltage.
Specifi cations are subject to change without notice.
Customers should verify actual device performance in their specifi c applications.
