SSRP130B1
DUAL ASYMMETRICAL OVERVOLTAGE
PROTECTION FOR TELECOM LINE
MAIN APPICATIONS
Where asymmetrical protection against lightning
strikes and other transient overvoltages is required :
Solid-State relays
SLIC with integrated ring generator
DESCRIPTION
The SSRP130B1 is a dual asymmetrical transient
voltage suppressor designed to protect a
solid-state ring relay or SLICs with integrated ring
generator from overvoltages.
The asymmetrical protection configuration is
necessary to allow the use of all different types of
ringing schemes.
