SEP0080Q38CB Product Details


The new SEP (SIDACtor Thyristor Ethernet/PoE Protector) series has a surge rating compatible with GR1089 inter-building and ITU K.20/21 Enhanced protection requirements. Targeted for high-speed applications such as 10BaseT, 100BaseT, and 1000BaseT, the SEP series maintains signal quality while providing robust protection for Ethernet and PoE applications. This latest silicon design innovation results in a capacitive loading characteristic that is constant with respect to the voltage across the component. This reduces distortion caused by typical solid-state protection solutions. Offered in a surface-mount, QFN package, the SEP provides small package size without sacrificing power and surge handling capabilities.

Features & Benefits

• Compatible with 1000Base-T 

• Balanced overvoltage protection 

• Low distortion 

• Low insertion loss 

• Low profile 

• SO-8 footprint compatible 

• Fails short circuit when surged in excess of ratings 

• RoHS Compliant and Halogen-Free 

• Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD-609A.01)

Applicable Global Standards

• TIA-968-A 

• TIA-968-B 

• ITU K.20/21 Enhanced Level 

• ITU K.20/21 Basic Level
