Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors The **P4SMA43CA** from **VISHAY** is a high-performance **surface-mount transient voltage suppressor (TVS) diode** designed to protect sensitive electronic circuits from voltage spikes and transient events. This component is part of the **P4SMA series**, which is widely recognized for its reliability and robust protection capabilities in various applications.  

With a **standoff voltage of 43V** and a **peak pulse power dissipation of 400W**, the P4SMA43CA effectively clamps transient voltages, safeguarding downstream components from damage caused by electrostatic discharge (ESD), lightning surges, and other electrical disturbances. Its **low clamping voltage** ensures minimal stress on protected circuits, maintaining system integrity.  

The **unidirectional configuration** of the P4SMA43CA makes it suitable for DC applications where transient suppression in a single polarity is required. The device features a **compact SMA (DO-214AC) package**, making it ideal for space-constrained PCB designs while providing high surge current handling.  

Common applications include **power supplies, communication equipment, automotive electronics, and industrial control systems**, where reliable overvoltage protection is critical. The P4SMA43CA meets industry standards for performance and durability, making it a trusted choice for engineers seeking robust transient suppression solutions.  

By integrating this TVS diode into circuit designs, manufacturers can enhance system resilience against unpredictable voltage transients, ensuring long-term operational stability.
