Application Specific Discretes
A.S.D
.™
SSRP130B1
®
Where asymmetrical protection against lightning
strikes and other transient overvoltages is required :
Solid-State relays
SLIC with integrated ring generator
MAIN APPICATIONS
SO8
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.
