Description and Introduction

10 V, 1 W silicon zener diode The **1N4740A** from ON Semiconductor is a widely used **Zener diode** designed for voltage regulation and protection in electronic circuits. With a **10V nominal Zener voltage (VZ)** and a tolerance of **±5%**, this component ensures stable reference voltages in various applications.  

Featuring a **1W power dissipation rating**, the 1N4740A is suitable for moderate power applications, including voltage clamping, surge suppression, and power supply stabilization. Its **axial-lead package** allows for easy through-hole mounting, making it a reliable choice for both prototyping and production environments.  

The diode operates efficiently within a **temperature range of -65°C to +200°C**, ensuring performance stability under varying conditions. Its **low dynamic impedance** enhances regulation accuracy, while a **maximum reverse leakage current (IR) of 5µA** minimizes power loss.  

Common applications include **voltage regulators, overvoltage protection circuits, and signal conditioning**. Engineers and hobbyists favor the 1N4740A for its balance of precision, durability, and cost-effectiveness.  

For optimal performance, proper heat dissipation and current-limiting resistors should be considered when integrating this Zener diode into circuit designs. Its dependable characteristics make it a staple in power management and protection solutions.
