BUL312FP Datasheet PDF - STMicroelectronics

DESCRIPTION 
The BUL312FP 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.
