TO-92
Description
The device is manufactured using high voltage
multi epitaxial planar technology for high switching Figure 1. Internal schematic diagram
speeds and high voltage capability. It uses a
cellular emitter structure with planar edge
termination to enhance switching speeds while
maintaining the wide RBSOA.
