UPGA301A
Nanosecond SCR SWITCH
PRODUCT PREVIEW
WATERTOWN DIVISION
DESCRIPTION
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 µA).
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.
IMPORTANT: For the most current data, consult MICROSEMI’swebsite:http://www.microsemi.com
