The P4SMA9.1A is a Transient Voltage Suppressor (TVS) Diode manufactured by JSCJ (JCET). This diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. It features a breakdown voltage of 9.1V and a peak pulse power dissipation of 400W, providing a high level of protection. The P4SMA9.1A is housed in a surface-mount SMA package, making it suitable for automated assembly. Supreme Components International is an authorised distributor of JSCJ (JCET) components, ensuring that you receive a genuine and high-quality product. This TVS diode is commonly used in applications such as telecommunications, industrial control, and consumer electronics to enhance system reliability and prevent damage from voltage surges. Its fast response time and low clamping voltage make it an effective solution for protecting sensitive circuitry.
