DIAC – Wikipedia
Getting started with eDesignSuite. Product is in volume production 0. Who We Are Management. Media Subscription Media Contacts. DIACs are also called “symmetrical trigger diodes” due to the symmetry of their characteristic curve. Their behavior is similar to that of a neon lampbut it can be more precisely controlled and takes place at a lower voltage.
Free Sample Add to cart. No commitment taken to produce Proposal: The diode remains in conduction until the current through it drops below a value characteristic for the device, called the holding currentI H.
No availability reported, please contact our Sales office. Diodes Solid state switches.

This page was last edited on 1 Juneat dbb3 Retrieved from ” https: The operation of the SIDAC is functionally similar to that of a spark gapbut is unable to reach its higher temperature ratings. However, where part-counts are to be kept low, simple relaxation oscillators are needed, and when the voltages are too low for practical operation of a spark gap, the SIDAC is an indispensable component.
Somewhat uncommon in most ddb3the SIDAC is relegated to the status of a special purpose device. Below this value, the diode switches back to its high-resistance, non-conducting state. Getting started with eDesignSuite 5: Marketing proposal for customer feedback. Once entering this conductive state going through the negative dynamic resistance region, the SIDAC continues to conduct, regardless of voltage, until the applied current falls below its rated holding current.

Views Read Edit View history. Product is in volume production only to support customers ongoing production. In general, SIDACs have higher breakover voltages diad current handling capacities than DIACs, so they can be directly used for switching and not just for triggering of another switching device.

Product is in design stage Target: The SIDAC remains nonconducting xiac the applied voltage meets or exceeds its rated breakover voltage.

This behavior is bidirectional, meaning typically the same for both directions of current. In many applications this function is now served by metal oxide varistors MOVsparticularly for trapping voltage transients on the power mains.
