TS420 Series
SENSITIVE 4A SCRs
September 2000 - Ed: 3
MAIN FEATUR ES:
DESCRIPTION
Thanks to highly sensitive triggering levels, the
TS 420 serie s is s uitable for all applica tions where
the available gate current is li mited, such as motor
control for hand tools, kitchen aids, overvoltage
crowba r protection for low power supplies, ...
Available in through-hole or surface-mount
pack ages, they provide an optim ized performance
in a limited space area.
