It can be used to conduct in both forward and reverse direction. It offers low resistance to \u003cstrong\u003ecurrent flow\u003c\/strong\u003e in one direction, and high resistance in the other direction. It is a two terminal device so it does not have a gate terminal like Triac to make it start conducting current, so it starts conducting only when applied voltage goes beyond the\u003cstrong\u003e break-over voltage\u003c\/strong\u003e. DB3 diac is used in rectifier circuits, switching devices, short circuiting protection purposes. The DIACs are used as a trigger device in various applications such as phase control circuits of motor speed control, light dimmers, heat controls, and many other control circuits.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBreakover Voltage (V\u003csub\u003ebo\u003c\/sub\u003e): 32V\u003c\/li\u003e\n\u003cli\u003eOutput Voltage (V\u003csub\u003eo\u003c\/sub\u003e): 5V\u003c\/li\u003e\n\u003cli\u003eRepetitive Peak On-State Current (I\u003csub\u003etrm\u003c\/sub\u003e): 2.0A\u003c\/li\u003e\n\u003cli\u003eBreakover Current (I\u003csub\u003ebo\u003c\/sub\u003e): 0.100mA\u003c\/li\u003e\n\u003cli\u003eTotal Power Dissipation (P\u003csub\u003etot\u003c\/sub\u003e): 150mW\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct Description\u003c\/strong\u003e\u003c\/p\u003e\u003cdiv style=\"text-align: left;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"DB3 Diac\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0300\/6424\/6919\/files\/DB3-Diac_600x600.jpg?v=1617179919\"\u003e\u003c\/div\u003e\u003cp\u003eWhen you start using it, the DIAC will be in blocking state and only very small \u003cstrong\u003eleakage current\u003c\/strong\u003e will flow. Once the applied voltage reaches the breakdown voltage the resistance of the DIAC drops abruptly and it starts conducting which leads to a sharp decrease in voltage across it and the current starts increasing, called the \u003cstrong\u003eConduction State\u003c\/strong\u003e. Most of the DIACs will be having the breakdown voltage around 30 Volts. If you want to turn the DIAC off, it will remain in the conducting state until the current reaches the particular value called the holding current, where\u003cstrong\u003e holding current\u003c\/strong\u003e is the minimum current that required for a device to keep it in the ON state and if the current fall below this level then it DIAC will stop conducting.\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAdditional Resources\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003e1\u003c\/span\u003e×\u003cspan\u003eDB3 Trigger Diode\u003c\/span\u003e\u003c\/p\u003e\u003cul class=\"features\"\u003e\u003c\/ul\u003e","brand":"mysite","offers":[{"title":"Default Title","offer_id":46019337683115,"sku":"CMP-QC0256","price":0.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/1205\/1115\/files\/Trigger-Diode.jpg?v=1767606488","url":"https:\/\/www.yuzxcn.com\/products\/db3-diac-trigger-diode","provider":"Yuzx","version":"1.0","type":"link"}
