This document presents an experimental comparison of several Triac devices under immunity tests, as described in the IEC 61000-4-4 standard. The immunity results are discussed according to the device technology and the gate current sensitivities. A discussion about relevance of dV/dt parameter and die area is carried on to differentiate the devices in term of immunity capability. Several guidelines can then be pointed out to design high immunity appliances.
This document presents an experimental comparison of several Triac devices subjected to fast transient voltages as described in the IEC 61000-4-4 standard. It evaluates the immunity of different Triac technologies, including Top, Mesa, and Planar structures, specifically for applications in home appliances like washing machines and refrigerators.
The comparison was performed on devices with a voltage rating of 800 V.
The dV/dt tests were performed at a 125 °C junction temperature.
