Getting started with eDesignSuite 5: When breakdown occurs, the diode enters a region of negative dynamic resistanceleading to dlac decrease in the voltage drop across the diode and, usually, a sharp increase in current through the diode. This behavior is bidirectional, meaning typically the same for both directions of current.

The operation of the SIDAC is functionally similar to that of a spark gapbut is unable to reach its higher temperature ratings.

Product is in volume production Evaluation: For other uses, see DIAC disambiguation.

Communications Equipment, Computers and Peripherals. Below this value, the diode switches back to its high-resistance, non-conducting state. Product is in design feasibility stage.

Their behavior is similar to that of a neon lampbut it can be more precisely bd3 and takes place at a lower voltage. Product is in design stage Target: The SIDAC remains nonconducting until the applied voltage meets or exceeds its rated breakover voltage.

Diodes Solid state switches. Product is under characterization. By using this site, you agree to the Terms of Use and Privacy Policy. Daic general, SIDACs have higher breakover voltages and current handling capacities than DIACs, so they can be directly used for switching and not just for triggering of another switching device.

No availability reported, please contact our Sales office. DIACs are also called “symmetrical trigger diodes” due to the symmetry of their characteristic curve.

Who We Are Management. Also referred to as a SYDAC Silicon thYristor for Alternating Currentbi-directional thyristor breakover diodeor more simply a bi-directional thyristor diode, it is technically specified as a bilateral voltage triggered switch.

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. The term is an acronym of “diode for alternating current”. Potentiometer digital Variable capacitor Varicap.
