CDLL252

Current Regulation - Diodes, Transistors Overview

The CDLL252 is a temperature-compensated Zener diode manufactured by Microchip Technology. It utilizes a leadless glass MELF (Metal Electrode Leadless Face) package, specifically the DO-213AA-2 form factor, designed for surface-mount applications. The device incorporates double plug construction with metallurgically bonded contacts to ensure high reliability and hermetic sealing. This component provides stable voltage regulation across an extended operating temperature range of -65°C to +175°C, making it suitable for demanding environments where standard silicon junctions may exhibit significant drift.
