Massive energy
The SHN Series is designed to meet high energy demands of network applications, providing top tier energy handling capabilities.
Product Features
0806in ~ 1812in
Operating Voltage: 12V ~ 60V
Surge Voltage Capability (10/700us): 1KV ~ 10KV
Surge Current Capability (5/320us): 25A ~ 250A
Operating Temperature: -55°C ~ 125°C
Compliant with IEC61000-4-5
Series Advantages
Small in size with quick response
Small in size and space-saving
The SHN series was developed to meet the energy requirements of circuit control boards in networking products, making it the highest-energy overvoltage protection component in the industry currently suitable for lightning protection in networking applications.
High reactivity, low inhibition
Traditional solutions (GDTs) carry the risk of follow-on current issues. The SHN series features a fast response time (<0.5ns), effectively suppressing overvoltage.
Extended impact resistance life
Higher surge durability than Sidactors, up to 10KV

Application Scenarios
As network systems become more integrated, multiple ports require protection from high-voltage damage.
Base station
Base station DC modules, often on rooftops or towers, are vulnerable to direct and induced lightning.
Routers
Routers and switches connected to outdoor lines may conduct lightning surges.
IDC
Lightning damage to servers can cause data loss and service interruptions.
Monitoring system
Outdoor surveillance devices, smart streetlights, and traffic sensors are exposed to lightning strikes.
Both indoor and outdoor network devices are at risk from lightning surges. Proper surge protection design is essential for reliability and safety—especially in devices like routers, switches, base stations, and optical fiber equipment.
