DESCRIPTION
The BUL310 and BUL310PI are manufactured using high voltage Multi Epitaxial Planar technology for high switching speeds and high voltage capability. They use 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.
