09:5909:59, 27 April 2024 diff hist +599‎ N Glossary:SIDAC ‎ Created page with "A SIDAC or Silicon Diode for AC is a 2-terminal electronic component comprising 5 semiconductor layers which abruptly switches from a non-conducting to a conducting state when a certain voltage is applied, typically in the region of 150 - 300V depending on the type. It then remains conducting until the current falls below a small holding current. It is similar in operation to a DIAC except for the higher threshold voltage. It has a few niche applications..."

Manufacturing defects are the principal cause of early life failures, but once these have all been shaken out the failure rate remains fairly low through the expected lifetime of a device. The failure rate then starts to climb as components begin to wear out. So plotting the failure rate against time gives a U-shaped curve, commonly known as the bathtub curve." current
