K0900S Datasheet, PDF (1/5 Pages) UN Semiconducctor INC – Sidac
Sidac
The sidac is a silicon bilateral voltage triggered switch with
greater power-handling capabilities than standard diacs.
Upon application of a voltage exceeding the sidac breakover
voltage point, the sidac switches 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.
