Description
C (2 or tab)
This 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
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.
