1/6
Pulse test : * tp = 5 ms, δ < 2 %
** tp = 380 μs, δ < 2%
To evaluate the maximum conduction losses use the following equation:
P = 0.75 x IF(AV) + 0.008 x IF2 (RMS)
STATIC ELECTRICAL CHARACTERISTICS (per diode)When the diodes 1 and 2 are used simultaneously:
ΔTj (diode 1) = P (diode 1) x Rth(j-c) (per diode) + P (diode 2) x Rth(C)
