DESCRIPTION

The BUL310FP 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.
