Trisils from the company are designed to protect ADSL/VDSL modems and similar high bit-rate communications equipment on the customer premises equipment side. Fully compatible with digital transmission standards such as ADSL2 and ADSL2+, the SMP80MC family of micro-capacitance transient surge arrestors is the first Trisil series for which the junction capacitance does not depend on the device breakdown voltage. The family of devices combines an 80-A repetitive peak pulse current rating with a low capacitance of only 12 pF, typical. The Trisil technology is said to offer superior performance, including a long service life without ageing, tight voltage tolerance, fast response times, and failsafe operation, compared to non-silicon alternatives, such as gas discharge tubes.
