CONFIGURATION
DESCRIPTION
The BUL903ED is manufactured using high
INTERNAL SCHEMATIC DIAGRAM
voltage Multi Epitaxial Planar technologyfor high
switchingspeeds and high voltage capability.
The device has been designed in order to
operate without baker clamp and transil
protection. This enables saving from 2 up to 10
components in the application.
