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.
