Description and Introduction

SURFACE MOUNT SILICON ZENER DIODE The **1SMA4735** is a surface-mount **Zener diode** designed for voltage regulation and transient suppression in electronic circuits. With a **5.1V** nominal breakdown voltage and a power dissipation rating of **1.5W**, this component is widely used in power supplies, signal conditioning, and protection applications.  

Housed in a compact **SMA (DO-214AC)** package, the 1SMA4735 offers reliable performance in a small footprint, making it suitable for space-constrained PCB designs. Its **±5% voltage tolerance** ensures stable regulation, while a low dynamic impedance enhances efficiency under varying load conditions.  

Key features include a **high surge current capability**, making it effective for clamping transient voltages in sensitive circuits. The diode operates over a **-65°C to +175°C** temperature range, ensuring stability in harsh environments.  

Common applications include **overvoltage protection**, voltage reference circuits, and load stabilization in consumer electronics, automotive systems, and industrial controls. Engineers favor the 1SMA4735 for its balance of precision, durability, and cost-effectiveness in both prototyping and mass production.  

When integrating this Zener diode, proper thermal management and current-limiting resistors are recommended to maximize performance and longevity. Its standardized footprint allows easy replacement with compatible alternatives if needed.
