The scr CS20-16IO1 thyristor manufactured from Ixys Corporation will suit your circuit"s needs and act as a bistable switch controlled by a current trigger. This device has a surge current rating of 280 A. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This SCR thyristor has an operating temperature range of -40 °C to 125 °C. Its repetitive peak forward blocking voltage is 1600 V, while its repetitive peak reverse voltage is 1600 V.
