Fixed Voltage SLIC Protector
RoHS
®
(T/R)
(G)
These DO-214AA unidirectional protectors are constructed with a SIDACtor device and an
integrated diode. They protect SLICs (Subscriber Line Interface Circuits) from damage
during transient voltage activity and enable line cards to comply with various regulatory
requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and
TIA-968-A (formerly known as FCC Part 68).
For details of specific design criteria, see Figure 6.31 in Section 6, “Reference Designs” of
this Telecom Design Guide).
