1N4700UR-1

Single Zener Diodes Overview

The Microchip Technology 1N4700UR-1 is a surface-mount Zener diode designed for voltage regulation applications. It utilizes the DO-213AA-2 package and operates within an extended temperature range from -65°C to +175°C junction temperature. The device provides a nominal Zener voltage of 3.3 V with a 5% tolerance, dissipating up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 50 nA at 2.8 V, a test current of 50 µA, and a forward voltage of 1.1 V at 200 mA.
