Marketing proposal for customer feedback. The DIAC, or ‘diode for alternating current’, is a diode that conducts current only after its breakover voltage has been reached momentarily.

Limited Engineering samples available Preview: From Wikipedia, the free encyclopedia. Media Subscription Media Contacts. Capacitor types Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch. Somewhat uncommon in most electronicsthe SIDAC is relegated to the status of a special purpose device. Chip Diodes allow the use of industry standard No commitment taken to produce Proposal: The devices are designed primarily to limit over-voltages on digital telecommunication lines and low voltage djac circuits.

Below this value, the diode switches back to its high-resistance, non-conducting state. Diodes Solid state switches.

The term is an acronym of “diode for alternating 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: In many applications this function is now served by metal oxide varistors MOVsparticularly for trapping voltage transients on the power mains. These are designed to tolerate large surge currents for the suppression of overvoltage transients. A new surface mount version is now available in SOT package, providing reduced space and compatibility with automatic pick and place equipment.

Their behavior is similar to that of a neon lampbut it can be more precisely controlled and takes place at a lower voltage. Contacts Learning Longevity Commitment. The Chip Diodes, are leadless, allowing designers to make real estate savings on PCB layouts.

DIAC – Wikipedia

This behavior is bidirectional, meaning typically the same for both directions of current. Distributor Name Region Stock Min. The diode remains in conduction until the current through it drops below a value characteristic for the device, called the holding currentI H. Product is in design stage Target: Computers and Peripherals Data Center. 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.
