DESCRIPTION
The BUL381 and BUL382 manufactured using
high voltage Multiepitaxial Mesa technology for
cost-effective high performance. They use a
Hollow Emitter structure to enhance switching
speeds.
The BUL series is designed for use in lighting
applications and low cost switch-mode power
supplies.
