Description
The BUF410A is manufactured using high voltage             Figure 1.   Internal schematic diagram
multi epitaxial planar technology for high switching
speeds and high voltage capacity. It uses a
cellular emitter structure with planar edge
termination to enhance switching speeds while
maintaining a wide RBSOA.
