CDLL4907A

Single Zener Diodes Overview

The CDLL4907A is a temperature-compensated Zener reference diode manufactured by Microchip Technology. It features a nominal Zener voltage of 12.8 V with a tolerance of ±5%. The device is designed for surface mount installation in the DO-213AA package, which measures 1.7 mm in diameter and 3.7 mm in length. It supports a maximum DC power dissipation of 500 mW at +50°C, with a derating factor of 4 mW/°C above this threshold. The component operates within an extended temperature range from -65°C to +175°C and exhibits a reverse leakage current of 15 µA at 8 V.
