US104S-N-4

Manufacturer Part Number
US104S-N-4
Description
Silicon Controlled Rectifiers
Manufacturer
Unisonic Technologies
Datasheet
UTC US104S/N
SCRs
DESCRIPTION
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.
