SIDAC (high-pressured triggering diode) characteristics:
 (1) the SIDAC trigger voltage is high, the scope is wide, at present may achieve 90V~330V.
(2) SIDAC has the negative resistance characteristic, passes condition voltage UT to be low, only then about 1.5V, therefore instantaneous can pass the big electric current.
(3) SIDAC is one kind of nonpolarity bidirectional trigger device, one cycle surge current ITSM may reach 20A, caused through the inductance to fill the electricity electrostatic discharge, produced the high energy high-pressured pulse.
 (4) SIDAC, once leads the bowel movement to be at the self-locking condition, only then winds through its outage or is smaller than time standby current IH, only will then shut off.　　      
(5)  The response speed is very quick (ns level).
(6) The form nimbly seals diverse. May use the DO-41, DO-201AD, TO-92, TO-220 plastic resin package. May also the single chip seal, may also the multi-chips seal in together.
(7) Uses the glass deactivation craft, the thermostable characteristic is good, the reliability is high.

Model application:　
the SIDAC application is very widespread. At present has used in the high energy the splendor (ignition) the electric circuit, the high pressure producer, the overvoltage protection, the oscillator, replacing aspects massively and so on thyristor electric circuit.　
(1) The high pressure producer electric circuit, this electric circuit may use in the air conditioning, the electric refrigerator, as the electronic sterilization, deodorizes uses.
(2) The low voltage input's electron has the splendor electric circuit, the pressurized lamp (mercury lamp, sodium lamp and so on) triggers, the daylight lamp to open the splendor, the fuel gas ignition, the cookware, the water heater ignition. SIDAC is one kind of silicon bidirectional voltage trigger switch component, with standard DIAC (DB3, DB4) compares, power control ability is bigger. When exerts the voltage surpasses its breakdown voltage, SIDAC passes a negative resistance area, but breakover to a low pass condition voltage. The breakover will continue the electric current; The interrupt or falls slightly maintains until the component below the electric current when the main application.

Main uses:
Xenon lamp trigger, pulse generator, high-voltage power supply, overvoltage protection, gasoline ignition installment, high-pressured sodium lamp trigger, halogen lamp trigger, liquid gas firing device, fluorescent lamp starter, on HID illumination starter light bulb's use: The light bulb protection bidirectional trigger series can reduce on the filament with SIDAC the component SIDAC in the light bulb electric circuit active voltage (RSM), makes the light bulb life to lengthen 1.5~5 times. Is suitable the situation which specially and maintains with difficulty in the outdoors signal light, uses the DO-15 diode seal, the easy installation. Spends a light bulb's money receiving in exchange for original many light bulb's life.

SIDAC Parts:
SIDAC component sidac is the silicon both sides voltage triggering development, it compared to standard diac power handling ability. If the application voltage surpasses the disruptive voltage spot, the sidac switch will open, it arrives at the low on status voltage through the negative resistance area. Will continue the electric conduction, is interrupted until the electric current or is lower than component's lowest standby current. the sidac component unique Bolivia obtuse chip ties firmly through the foundation, the reliable barrier prevents the chip to tie the pollution, thus guarantees the long-term reliability and the steady state response. we may to have custom-made the design application to provide in this data sheet various components' other models. Please relate with the factory, understands more information.
