TS420 Series
SENSITIVE
4A SCRs
September 2000 - Ed: 3
MAIN FEATURES:
DESCRIPTION
Thanks to highly sensitive triggering levels, the
TS420 series 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.
