DESCRIPTION
The BUL67 is manufactured using high voltage
Multiepitaxial Mesa technology for cost-effective
high performance. It uses a Hollow Emitter
structure to enhance switching speeds.                 INTERNAL SCHEMATIC DIAGRAM
The BUL series is designed for use in lighting
applications and in low cost switch-mode power
supplies.
