A: The value of R
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
D. The static characteristics in Figures 1 to 6,12,14 are obtained using 80 µs pulses, duty cycle 0.5% max.
E. These tests are performed with the device mounted on 1 in
SOA curve provides a single pulse rating.
