DESCRIPTION:
SURFACE MOUNT SILICON
CURRENT LIMITING DIODES
The CENTRAL SEMICONDUCTOR CDCLD200,
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.
