JANTX1N5550 switching diode

Tested devices were manufactured by Semtech and Micro Semiconductor. Failure rate of Semtech diodes exceeded 50% in all three test groups. Failure mode could not be precisely determined.

Source record↗

JANTX1N5552 switching diode

Switching diodes manufactured by Micro Semidonductor and Semtech were tested. In groups 2 and 3 there were no Micro Semiconductor catastrophic failures. Testing of both lots was stopped in group 1 test because of 50% failure rate.

Source record↗

JANTX1N5554 switching diode

Micro Semiconductor and Semtech diodes were tested. In group 1 tests Micro Semiconductor and Semtech lot testing was stopped because of excess failure rate. Failure analysis was performed on group 1 and 3 because of apparent failure mode.
