Designed for high current
narrow-pulse switching
applications where size and current
handling capability are critical.
These devices may be triggered on
using low power logic drivers from
(+0.8 V at 200
碌A(chǔ)).
Epoxy packaged, oxide passivated planar
SCR chips with metallurgic bonds on both
sides to achieve high reliability. Internal
wire bond connection allows high current
surge capability for narrow pulse
applications.

nanosecond SCR switches include
automotive collision avoidance
systems, laser drivers, photo-flash
quenching circuits, specially
developed circuits for the emerging
digital imaging range finders and
communication markets.
