The P4SMA13A is a Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. It features a power dissipation of 400W and a reverse standoff voltage of 13V. The P4SMA13A is housed in a compact SMA (Surface Mount Assembly) package, making it suitable for high-density circuit board applications. 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 telecommunications equipment, industrial controls, computers, and consumer electronics to enhance system reliability and prevent damage from voltage surges.
