PRODUCT SELECTION

Thyristor surge suppressors

Thyristor surge suppressors switch into a low-voltage conducting state. Off-state voltage, switching voltage and holding current are separate selection parameters. Peak pulse current is presented at 10/1000 µs so the A, B and C grades can be compared on the same basis.
