STMicroelectronics BUL903
The BUL903ED is manufactured using high voltage Multi Epitaxial Planar technology for high switching speeds 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.APPLICATIONS
