Fixed Voltage SLIC Protector
RoHS
These DO-214AA unidirectional protectors are constructed with a
SIDACtor
庐
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, 鈥淩eference Designs鈥?of
this
Telecom Design Guide).
