DESCRIPTION
FEATURESDual center tap rectifier suited for switchmode
power supply and high frequency DC to DC
converters.

applications.
ABSOLUTE MAXIMUM RATINGS1/6
Pulse test : * tp = 5 ms, δ < 2 %
** tp = 380 μs, δ < 2 %
To evaluate the conduction losses use the following equation :
P = 0.65 x IF(AV) + 0.016 x IF2 (RMS)
STATIC ELECTRICAL CHARACTERISTICS (Per diode)
RECOVERY CHARACTERISTICSWhen the diodes 1 and 2 are used simultaneously :
Tj-Tc (diode 1) = P(diode 1) x Rth(j-c) (Per diode) + P(diode 2) x Rth(c)
