Description and Introduction

SILICON 400 mW ZENER DIODES The **1N747ATR** from National Semiconductor is a high-performance Zener diode designed for voltage regulation and protection in electronic circuits. As part of the 1N747 series, this component offers a nominal Zener voltage of **3.9V** with a tolerance of **±5%**, making it suitable for precision applications where stable reference voltages are critical.  

Constructed with robust silicon technology, the 1N747ATR provides reliable reverse breakdown characteristics, ensuring consistent performance under varying load conditions. Its **500mW power dissipation rating** allows it to handle moderate power levels, while its compact **DO-35 package** ensures easy integration into a wide range of circuit designs.  

Common applications include voltage clamping, surge suppression, and voltage stabilization in power supplies, signal conditioning circuits, and consumer electronics. The diode’s low dynamic impedance enhances its efficiency in maintaining stable output voltages despite fluctuations in input or load conditions.  

Engineers and designers favor the 1N747ATR for its dependable performance, industry-standard specifications, and compatibility with automated assembly processes. Whether used in industrial controls, telecommunications, or portable devices, this Zener diode remains a trusted solution for maintaining circuit integrity and precision voltage regulation.
