Use Advantages
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 Aero/Space). MIL-S- 19500/ 240 approvals.
Available up to JANTXV-1 level.
