This three-chip SIDACtor solution offers a guaranteed balanced protection, based on a
Littelfuse patent (US Patent 4,905,119). The ‘Y’ configuration offers identical metallic and
longitudinal protection in one through-hole modified TO-220 package. For primary
protection applications, devices with higher holding current and integrated failsafe options
are available.

SIDACtor devices enable equipment to comply with various regulatory requirements
including GR 1089, ITU K.20,K.21 and K.45, IEC 60950, UL 60950, and TIA-968-A
(formerly known as FCC Part 68).
