A SIDAC is a high power breakover diode. It diverts lightning surges away from sensitive elec- tronic components when used as a transient sup- pressor in telephone applications. Lamp starters use the device to generate the high starting voltage pulse. These applications result in turn-on switching stress because of current amplitudes and rates conducted by the SIDAC. The ability of the device to switch on quickly and survive high pulse current ampli- tudes determines device reliability and switching losses.
