The P4SMA300A is a high-performance 300V, 400W Transient Voltage Suppressor (TVS) diode manufactured by Diotec. This surface mount device, housed in an SMA package, provides exceptional protection against voltage transients, such as those caused by electrostatic discharge (ESD), inductive load switching, and lightning strikes. As an authorised distributor of Diotec components, Supreme Components International ensures the authenticity and quality of this product. The P4SMA300A is designed to clamp transient voltages to a safe level, preventing damage to sensitive electronic components. Its fast response time and low clamping voltage make it suitable for a wide range of applications, including telecommunications equipment, industrial controls, and consumer electronics. This TVS diode offers a reliable and cost-effective solution for enhancing the robustness and longevity of electronic circuits. Its compact size and surface mount design simplify installation and integration into existing designs.
