Description and Introduction
ARK Electronics - Surface Mount Transient Voltage Suppressors Peak Pulse Power 400W Breakdown Voltage 6.8 to 550V The **P4SMA440A** from **VISHAY** is a high-performance **surface-mount transient voltage suppressor (TVS) diode** designed to protect sensitive electronic circuits from voltage spikes and transients. This component is part of the **P4SMA series**, which is widely used in applications requiring robust overvoltage protection, such as telecommunications, industrial systems, and consumer electronics.  
With a **standoff voltage of 440V** and a **breakdown voltage range of 488V to 539V**, the P4SMA440A offers reliable clamping performance for high-voltage environments. Its **peak pulse power dissipation of 400W (10/1000μs waveform)** ensures effective suppression of transient surges, safeguarding downstream components. The device features a **low clamping voltage**, minimizing stress on protected circuits while maintaining fast response times.   Encased in a **DO-214AC (SMA) package**, the P4SMA440A is compact and suitable for automated PCB assembly. Its **unidirectional polarity** makes it ideal for DC applications, providing protection against positive voltage transients.   Engineers favor this TVS diode for its **high surge capability**, **low leakage current**, and **consistent performance** under harsh conditions. Whether used in power supplies, data lines, or automotive systems, the P4SMA440A delivers dependable overvoltage protection, enhancing system reliability and longevity. |
