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.
Compliance with the highest telecommunications standards such as GR-1089 core, ITU-T-K20/K21, VDE0433, VDE0878, IEC 61000-4-5, and FCC part 68
Ultralow-voltage versions down to 8 V, suitable for protecting low-voltage transformers in T1/E1 and Ethernet links without saturation
High-voltage versions up to 400 V to prevent firing with power crossing, so lowering maintenance costs in remote central offices by saving PTC cost and fuse replacement
Availability in low (LC) and micro (MC) capacitance levels to be compatible with digital transmissions such as ADSL2 and ADSL2+
A new generation of discrete surge suppressors will soon be available, offering additional cost savings.
