Maximum ratings and electrical characteristics
O
Rating at 25 C ambient temperature unless otherwise specified. Single phase, half wave, 60Hz, resistive or inductive load.
For capacitive load, derate current by 20%.
Low profile surface mounted application in order to
optimize board space.
Low power loss, high efficiency.
High current capability, low forward voltage drop.
Ultra high-speed switching.
Silicon epitaxial planar chip, metal silicon junction.
Suffix "G" indicates Halogen-free part, ex.SK52AG.
Lead-free parts meet environmental standards of
MIL-STD-19500 /228
