Halogen-Free μsec
• Blocking voltage • Thru hole and surface
(VDRM) capability mount packages
Main Features — up to 600V
• Surge
Symbol Value Unit capability > 9.5Amps
IT(RMS) 0.8 A
VDRM/VRRM 400 to 600 V Applications
IGT 3 to 5 mA The LX8 EV Series is especially designed for low current
applications such as heating controls in hair care products,
as well as replacement of mechanical switch contacts
