CDCLD200 CDCLD400 CDCLD500 www.centralsemi.com DESCRIPTION: SURFACE MOUNT SILICON The CENTRAL SEMICONDUCTOR CDCLD200, CURRENT LIMITING DIODES CDCLD400, and CDCLD500 are Current Limiting Diodes (CLDs) specifically designed for applications requiring a constant current over a wide voltage range. The series is designed with a unique process that holds regulator current constant over temperature excursions (zero temperature coefficient). The devices are available in the thermally efficient DPAK package outline.
