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. "S" level screening capability to Source Control Drawings.
