ST’s discrete surge suppressors, or Trisils™, protect sensitive equipment against lightning strikes and power crossing. They support applications such as power-line modems, Ethernet, POTs, CO/CP, set-top boxes, gateways and telecom lines.
ST, leader in crowbar suppressors, is launching a new generation of products adopting industry-standard part numbering for easy cross reference and drop-in replacement.
Available from 72 to 310 V in SMB packages, these devices offer the highest surge current capability for a given budget.
