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.
Notes:
- Absolute maximum ratings measured at TA= 25ºC (unless otherwise noted).
- Components are bidirectional (unless otherwise noted).

Notes:
- Peak pulse current rating (IPP) is repetitive and guaranteed for the life of the product as long as it returns to 25C° between surges
- IPP ratings applicable over temperature range of -40ºC to +85ºC
- The components must initially be in thermal equilibrium with -40°C < TJ < +150°C
