概述

Description

MMSZ4707T1G is a surface-mount Zener diode from the MMSZ family. It has a nominal Zener (reverse-breakdown) voltage of about 47 V and a power rating of roughly 0.5 W (25°C). It is used for voltage regulation, clamping, and simple overvoltage protection in low-to-medium power circuits. In normal operation it is reverse-biased and conducts when the input reaches the Zener voltage, helping stabilize or limit voltages. The T1G suffix indicates a specific packaging/ordering variant (tape-and-reel) per the manufacturer’s datasheet. For exact electrical parameters (voltage tolerance, dynamic resistance, knee current, reverse leakage, and precise package dimensions), refer to the latest datasheet.
