UNISONIC TECHNOLOGIES CO., LTD
US104S/N
SCRS
DESCRIPTION
Thanks to highly sensitive triggering levels, the UTC
US104S
is suitable for all applications where the available gate current is
limited, such as motor control for hand tools, kitchen aids,
overvoltage crowbar protection for low power supplies, ...
Available in through-hole or surface-mount packages, they
provide an optimized performance in a limited space area.
