RURP30120
Data Sheet January 2000
30A, 1200V Ultrafast Diode
The RURP30120 is an ultraf ast diode with soft recovery
characteristic (t
< 110ns). It has low forward voltage drop
rr
and is silicon nitride passivated ion-implanted epitaxial planar
construction.
This device is intended for use as a freewheeling/clamping
diode and rectifier in a variety of switching power supplies
and otherpowerswitchingapplications. Its low stored charge
and ultrafast recovery with soft recovery characteristic
minimize ringing and electrical noise in many power
switching circuits, reducing power loss in the switching
transistors.
Formerly developmental type TA49031.
