Baseband Protection (Voice-DS1)
Description
SIDACtor
®
Series - SMA
SIDACtor
®
SMA Series are designed to protect
baseband equipment such as phones, faxes, modems,
line cards, CPE and DSL from damaging overvoltage
transients.
The series provides a surface mount solution that
enables equipment to comply with global regulatory
standards.
Electrical Characteristics
Features and Benefits
• Low voltage overshoot
• Low on-state voltage
• Does not degrade
surge capability after
multiple surge events
within limit.
• Fails short circuit when
surged in excess of
ratings
• Low capacitance
