A. The value of R

θJA

is measured with the device mounted on

FR-4 board with 2oz. Copper, in a still air environment with T

A

=25°C. The

value in any given application depends on the user's specific board design.

B. The power dissipation P

D

is based on T

J(MAX)

=150°C, using

≤

10s junction-to-ambient thermal resistance.

C. Repetitive rating, pulse width limited by junction temperature T

J(MAX)

=150°C. Ratings are based on low frequency and duty cycles to keep

initialT

J

=25°C.

D. The R

θJA

is the sum of the thermal impedence from junction to lead R

θJL

and lead to ambient.

E. The static characteristics in Figures 1 to 6 are obtained using <300µs pulses, duty cycle 0.5% max.

F. These curves are based on the junction-to-ambient thermal impedence which is measured with the device mounted on 1in

2

FR-4 board with

2oz. Copper, assuming a maximum junction temperature of T

J(MAX)

=150°C. The SOA curve provides a single pulse rating.
