KEY FEATURES
DESCRIPTION
The UPGA301Ae3 is Designed for Epoxy packaged, oxide passivated planar
high current narrow-pulse switching SCR chips with metallurgic bonds on both
applications where size and current sides to achieve high reliability. Internal
Very low thermal resistance package
Efficient heat path with integral
locking bottom metal tab
handling capability are critical.
wire bond connection allows high current
Full metallic bottom eliminates flux
entrapment
RoHS Compliant with e3 suffix
High speed switching capability
Compatible with high-speed insertion
Low profile height of 1 mm
These devices may be triggered on surge capability for narrow pulse
using low power logic drivers from applications.
(+0.8 V at 200 μA).
