Products Detail

The series features unidirectional TVS devices for thru-hole mounting in a hermetically sealed DO-13 metal package. They suppress transients up to 1500 watts at 10/1000 µs and clamp transients in less than 100 picoseconds. The working voltage range spans 5 V to 171 V. These devices protect against transients from inductive switching, induced RF, and secondary lightning effects per IEC61000-4-5. They are also effective for ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4, and are used in airborne avionics and electrical systems. Military qualified versions (JAN, JANTX, JANTXV) are available for tighter tolerance 'A' suffix devices.
