SIDAC Diode 180V 1A(RMS) 20A 2-Pin DO-15X Bulk

Inquiry Add To Bom

K2002G General Description

The SIDAC is a silicon bilateral voltage triggered switch. 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. Conductioncontinues until the current is interrupted or drops below the minimum holding current of the device.SIDACs feature glass-passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments.
