Electronic ballast for fluorescent lighting 1
SOT-82
Description
The device is manufactured using high voltage
multi-epitaxial planar technology for high
switching speeds and medium voltage capability.
It uses a cellular emitter structure with planar Figure 1. Internal schematic diagram
edge termination to enhance switching speeds
while maintaining the wide RBSOA. The device is
designed for use in lighting applications and low
cost switch-mode power supplies.
