Reverse Transfer Capacitance

A: The value of R θJA is measured with the device mounted on 1in

2 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. The current rating is based on the t ≤ 10s thermal

resistance rating.

B: Repetitive rating, pulse width limited by junction temperature.

C. The R θJA is the sum of the thermal impedence from junction to lead R θJL and lead to ambient.

D. The static characteristics in Figures 1 to 6,12,14 are obtained using <300

µs pulses, duty cycle 0.5% max.

E. These tests are performed with the device mounted on 1 in

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

A=25°C. The

SOA curve provides a single pulse rating.
