Sidac for Gas Igniter Circuit
Solutions
Design Notes:
- Protection Application:
- Sidac devices are used as switch on device for Igniter Circuits. Operation Note: The resistor is usually chosen to achieve a spark interval of 100 – 250 mili second.
- Solution Description:
- For a voltage exceeding the Sidac breakover voltage point, the Sidac swathes on through a negative resistance region to a low on-state voltage. Conduction continues until the current is interrupted or drops below the minimum holding current of the device. K2400G is commonly used in this application.
- Companion Solutions:
- K277 is new Sidac for high energy ignition systems which could replaces many GDTs.
- Regulatory Issues:
- Does not apply.
- Unique Features:
- Does not apply.
- Application Warnings:
- Does not apply.
