SIDACtor ® Protection Thyristors
Broadband Optimized™ Protection
SEP Biased Series - 5x6 QFN
Description
The new SEP (SIDACtor 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 device. 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.
