Semtech's high reliability products include Qualified Products List (QPL) and non-QPL rectifiers, transient voltage suppression (TVS) and Zener diodes in axial and surface-mount packages, as well as assemblies in catalog and custom configurations. A new range of Commercial Off-The-Shelf (COTS) diodes and power management devices round out the offerings. Designed to operate across a wide temperature range in unforgiving environments, these devices are ideal for Aerospace, Industrial and Military applications.

Rectifier Diodes

Semtech’s discrete rectifier diodes are hermetic, non-cavity, double plug construction with category I metallurgical bonds suitable for operation at temperatures ranging from -65°C to +175°C. This makes them ideal for aerospace, military and industrial applications. Semtech's diodes are listed on the Land & Maritime Qualified Products List and qualified to JAN, JANTX, JANTXV and JANS (Space) quality levels in both axial and surface mount packages. Semtech offers the capability to perform custom screening and processing, as well as up-screening to Space grade equivalent and above. 

Semtech also offers catalog epoxy encapsulated rectifier assemblies (modules) and non-encapsulated, higher power density, open frame construction assemblies (ISOPACs). 

Ideal for industrial, military and aerospace applications, our TVS diodes are hermetic, non-cavity, double-plug construction with category I metallurgical bonds. They are suitable for operation at temperatures ranging from -65°C to 175°C.

Semtech's TVS diodes are listed on the Land & Maritime Qualified Products List and are qualified to JAN, JANTX, JANTXV, and JANS (Space) quality levels in both axial and surface mount packages.

They have available peak pulse power ratings of 500W and 1.5kW. 

Semtech offer the capability to perform custom screening and processing, as well as up-screening to Space grade equivalent and above.

Semtech also offers catalog high power (15kW, 60kW and 90kW), epoxy encapsulated TVS assemblies for airborne and shipboard applications. Custom configurations to your own specifications including screening and quality conformance inspection testing are also available.

Zener Diodes

Ideal for industrial, military and aerospace applications, our Zener diodes are hermetic, non-cavity, double-plug construction with category I metallurgical bonds. They are suitable for operation at temperatures ranging from -65°C to 175°C.

Semtech's Zener diodes are listed on the Land & Maritime Qualified Products List and are qualified to JAN, JANTX, JANTXV, and JANS (Space) quality levels in both axial and surface mount packages.

They have available power ratings of 1.5W and 5W.

Semtech offer the capability to perform custom screening and processing, as well as up-screening to above  Space grade.

Custom configurations to your own specifications including screening and quality conformance inspection testing are also available. For non-encapsulated, higher power density, open frame construction assemblies, see ISOPACs.
