MUR1620CT, RURP820CC
8A, 200V Ultrafast Dual Diodes
The MUR1620CT and RURP820CC are ultrafast dual
diodes with soft recovery characteristics (t
rr
< 25ns). They
have low forward voltage drop and are silicon nitride
passivated ionimplanted epitaxial planar construction.
These devices are intended for use as freewheeling/
clamping diodes and rectifiers in a variety of switching power
supplies and other power switching applications. Their low
stored charge and ultrafast soft recovery minimize ringing
and electrical noise in many power switching circuits
reducing power loss in the switching transistors.
Formerly developmental type TA09224.
