The Bourns® MSP® Protector Advantage
Multi-Stage Protection
2430-41-G-MSP
The Best of Two Technologies - Bourns® MSP® 5-pins
and station protectors provide superior protection
by combining the high energy handling of a threeelectrode Gas Discharge Tube with the quick response
of solid-state Metal Oxide Varistors (MOVs).
2378-35-HS
2377-45-HS-IDC
Solid-state devices react quickly to electrical surges but
2410-39-G-MSP
generally cannot handle high energy surges. Multi-Stage
Protectors limit the incoming surge with the MOVs as
the GDT activates to handle the bulk of the energy by
directing it safely to ground, away from personnel and
equipment.
Low Capacitance - The low capacitance of Bourns®
MSP® products makes them ideal for broadband
applications such as ADSL2+ and VDSL2. Our new
PPTCR-based 5-pins with overcurrent protection offer
industry-leading performance with low resistance and
capacitance.
No Air Back Up Gap - Bourns® MSP® devices do not have
an air Back Up Gap (BUG), thereby eliminating BUGrelated contamination within the protector as a potential
cause of faults on the line.
2377-45-HS
Switch-Grade Fail-Short - Unlike technologies that
require a solder pellet to melt or an insulating material
to burn away, Bourns® MSP® units feature a SwitchGrade Fail-Short, which activates in response to an
extended overvoltage to provide exceptional fire
protection.
Proprietary Low Work Function GDT Coating - This feature
ensures low heating and high efficiency in handling
surges.
Long Life, Proven Reliability - Bourns® MSP® products
have a proven record of reliability with millions of
protectors deployed worldwide.
