DB3 Bidirectional DIAC

ST Code dlac Conduct Blog. Getting started with eDesignSuite. Is a positive power supply mandatory for my application, or could a negative output work also? When breakdown occurs, dkac diode enters a region of negative dynamic resistanceleading to eiac decrease in the voltage drop across the diode and, usually, a sharp increase in current through the diode.

Somewhat uncommon in most electronicsthe SIDAC is relegated to the status of a special purpose device.

Communications Equipment, Computers and Peripherals. In general, SIDACs have djac 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. Product is under characterization. Product is in volume production only to support customers ongoing production.

Capacitor types Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch. Diodes Solid state switches. Marketing proposal for customer feedback. Their behavior is similar to that of a neon lampbut it can be more precisely controlled and takes place at a lower voltage.

Menu Products Explore our product portfolio. Key Features V BO: Once entering this conductive state going through the negative dynamic resistance region, the SIDAC continues to conduct, regardless of voltage, until the db current falls below its rated holding current.


Limited Engineering samples available Preview: 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.

The term is an acronym of “diode for alternating current”. In other projects Wikimedia Commons.

How to implement a SCR or a Triac in a hybride relay application. IoT for Smart Things. The diode remains in conduction until the current through it drops below a value characteristic for the device, called the holding currentI H.
