RM
-values
q
Soft recovery behaviour
q
Epoxy meets UL 94V-0
Applications
q
Antiparallel diode for high frequency
switching devices
q
Antisaturation diode
q
Snubber diode
q
Free wheeling diode in converters
and motor control circuits
q
Rectifiers in switch mode power
supplies (SMPS)
q

Advantages
q
Avalanche voltage rated for reliable
operation
q
Soft reverse recovery for low
EMI/RFI
q
Low I
RM
reduces:
- Power dissipation within the diode
- Turn-on loss in the commutating
switch
