Description and Introduction

3 Watt Plastic Surface Mount Zener Voltage Regulators The **1SMB5943BT3G** from ON Semiconductor is a high-performance Zener diode designed for voltage regulation and transient suppression in various electronic circuits. This surface-mount device offers a nominal Zener voltage of **43V** with a power dissipation of **3W**, making it suitable for applications requiring stable voltage references or overvoltage protection.  

Encased in a compact **SMB (DO-214AA)** package, the 1SMB5943BT3G provides excellent thermal characteristics and reliability. Its robust construction ensures efficient handling of transient voltage spikes, making it ideal for power supplies, automotive systems, and industrial equipment. The diode features a tight voltage tolerance and low leakage current, ensuring precise regulation under varying load conditions.  

Key specifications include a **5% tolerance** on the Zener voltage and an operating temperature range of **-65°C to +150°C**, allowing for deployment in demanding environments. Additionally, its lead-free and RoHS-compliant design aligns with modern environmental standards.  

Engineers and designers favor the 1SMB5943BT3G for its balance of performance, size, and durability, making it a dependable choice for circuit protection and voltage stabilization needs.
