DESCRIPTION
MAIN PRODUCT CHARACTERISTICS
STPR620CT/CF/CFPPulsetest:
*tp=5ms, δ<2%tp=380μs,δ <2%
ELECTRICAL CHARACTERISTICS
STATIC CHARACTERISTICS evaluate the conduction losses use the following equation:
P=0.78xIF(AV)+ 0.070xIF2 (RMS)
RECOVERY CHARACTERISTICSWhen the diodes1 and2 are used simultaneously: Tj(diode1)= P(diode1)x Rth(j-c) (Per diode)+ P(diode2)x Rth(c)
