DESCRIPTION
The device is manufactured using high voltage
Multi Epitaxial Planar technology for high
switching speeds and high voltage capability. It
uses a Cellular Emitter structure with planar edge
termination to enhance switching speeds while
maintaining a wide RBSOA.
The BUL series is designed for use in lighting
applications and low cost switch-mode power
supplies.
