STMicroelectronics DB3 DIAC 36V, 2A, 2-Pin DO-35

These are designed to tolerate large surge currents for the suppression of overvoltage transients. The operation of the SIDAC is functionally similar to that of a spark gapbut is unable to reach its higher temperature ratings.

The diode remains in conduction until the current through it drops below a value characteristic for the device, called rb3 holding currentI H. No availability reported, please contact our Sales office.


However, where part-counts are to be kept rb3, 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. Standard Pack Production Pack. The product detailed below complies with the specifications published by RS Components.

Below this value, the diode switches back to its high-resistance, non-conducting state. In many applications this function is now served by metal oxide eiac MOVsparticularly for trapping voltage transients on the power mains.

Chip Diodes allow the use of industry standard 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. Diodes Solid state switches.

Is a positive power supply mandatory for my application, eb3 could a negative output work also?
