  • FEC CV400 - Diode Tester The CV400 tests silicon Transient Voltage Suppressor (TVS) diodes, uni-polar and bipolar. The waveform used for the main test is the 10/1000µs waveform. The tester can also produce 8/20µs and 6/70µs exponential waveforms, 8.3ms half sine and rectangle pulses. These tests not only prove the ability of the DUT to endure the pulses without failure, but also measure the peak voltage across the device during the pulse. The CV400 can also measure the VZ of the device both before and after the pulse. Limits may be applied to the absolute value of these VZ tests and to the difference between them. If the initial VZ is outside the programmed limits, the part can be rejected and the main pulse not be applied. IR can be measured before and after the main pulse. This test is intended to detect damage due to the main pulse which is too slight to be detected by the main pulse or VZ test. The tester is designed to work with one or two automatic handlers or manual test stations. Bin sort outputs sort the parts into good devices that pass all requirements, several classes of rejects, and those parts which were not completely tested because of some fault condition.

  • FEC200E - Diode Tester This is a successor to our longstanding and successful tester FEC200. The FEC200 is described in detail on this site. The "E" version has all of the same capabilities as the original tester. In addition the "E" version has hardware and software enhancements to support various optional external test stations. These stations may add additional tests such as those used to test TVS devices. They may also extend the voltages and currents available in the host tester.
