NTE6415 thru NTE6419

Bidirectional Thyristor Diodes (SIDAC)

Description:

The NTE6415 through NTE6419 SIDAC devices are silicon bilateral voltage triggered switches 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 will continue until the current is interrupted or drops below the
minimum holding current of the device.
