| Philips Semiconductors Product specification Breakover diodes BRS212 series GENERAL DESCRIPTION A range of bidirectional, breakover diodes in a two terminal, surface mounting, plastic envelope. These devices feature controlled breakover voltage and high holding current together with high peak current handling capability. Their intended application is protection of line based telecommunications equipment against voltage transients.
