Description and Introduction
ARK Electronics - Surface Mount Transient Voltage Suppressors Peak Pulse Power 400W Breakdown Voltage 6.8 to 550V The **P4SMA170A** from **VISHAY** is a high-performance **surface-mount TVS diode** designed to protect sensitive electronic circuits from voltage transients, including electrostatic discharge (ESD) and lightning-induced surges. This component belongs to the **SMA power TVS diode series**, offering robust clamping performance in a compact **DO-214AC (SMA) package**.  
With a **standoff voltage of 170V** and a **peak pulse power dissipation of 400W**, the P4SMA170A ensures reliable overvoltage protection in applications such as **industrial controls, telecommunications, and automotive systems**. Its low clamping voltage and fast response time make it ideal for safeguarding data lines, power supplies, and communication interfaces against transient voltage spikes.   Key features include **bidirectional polarity**, ensuring protection against both positive and negative surges, and a wide operating temperature range of **-55°C to +150°C**, making it suitable for harsh environments. The P4SMA170A complies with industry standards, including **AEC-Q101** for automotive applications, ensuring high reliability under demanding conditions.   Engineers favor this TVS diode for its **high surge capability**, compact form factor, and consistent performance, making it a dependable choice for transient voltage suppression in modern electronic designs. |
