Features
●
International standard package
●
Planar passivated chips
●
Very short recovery time
●
Extremely low switching losses
●
Low IRM-values
●
Soft recovery behaviour
●
Epoxy meets UL 94V-0
Applications
●
Antiparallel diode for high frequency
switching devices
●
Antisaturation diode
●
Snubber diode
●
Free wheeling diode in converters
and motor control circuits
●
Rectifiers in switch mode power
supplies (SMPS)
●
Inductive heating
●
Uninterruptible power supplies (UPS)
●
Ultrasonic cleaners and welders
Advantages
●
Avalanche voltage rated for reliable
operation
●
Soft reverse recovery for low
EMI/RFI
●
Low IRM reduces:
- Power dissipation within the diode
- Turn-on loss in the commutating
switch
