Silicon Rectifier Diodes
Use Advantages
1 N645-I
thru
1 N649-I
DO-35 Glass Package
Used as a general purpose rectifier in power supplies, or for clipping and
steering applications.
High performance alternative to small signal diodes where space does not
permit
use of power rectifiers.
May be used in hostile environments where hermeticity and reliability are
important i.e.
(Military and Aerospace). MlL-S-19500/240 approvals.
“S’ level screening capability to Source Control Drawings.
