Description and Introduction

5 Watt Surmetic 40 Silicon Zener Diodes The **1N5349B** from **ON Semiconductor** is a high-power Zener diode designed for voltage regulation and protection in various electronic circuits. With a nominal Zener voltage of **12V** and a power dissipation rating of **5W**, this component is well-suited for applications requiring stable voltage references or transient suppression.  

Featuring a robust axial-lead package, the **1N5349B** ensures reliable performance in demanding environments. Its tight voltage tolerance and low dynamic impedance make it ideal for precision voltage regulation in power supplies, industrial controls, and automotive systems. The diode operates efficiently within a wide temperature range, maintaining consistent performance under varying conditions.  

Key specifications include a **maximum reverse leakage current** of **5µA** and a **Zener impedance** of **3.5Ω**, ensuring minimal power loss and effective noise filtering. The **1N5349B** is also designed to handle high surge currents, enhancing its durability in circuits exposed to voltage spikes.  

Engineers and designers often select this Zener diode for its balance of performance, reliability, and cost-effectiveness. Whether used in voltage clamping, overvoltage protection, or as a reference element, the **1N5349B** provides a dependable solution for maintaining circuit stability.
