KxxxxSA/KxxxxSB Series Sidac
DESCRIPTION:
Rev.2.3
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 currentis interrupted or drops
below the minimum holding current of the device.
APPLICATIONS:
High-voltage lamp ignitors
Natural gas ignitors
Gas oil ignitors
SMA/SMB
High-voltage power supplies
