The P4SMA39A is a Transient Voltage Suppressor (TVS) Diode from JSCJ (JCET), available at Supreme Components International, an authorised distributor. This diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), inductive load switching, and other transient voltage events. With a power dissipation rating of 400W and a reverse standoff voltage of 39V, the P4SMA39A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its SMA (Surface Mount Assembly) package allows for easy integration into printed circuit boards. This TVS diode is suitable for a wide range of applications, including automotive electronics, industrial control systems, telecommunications equipment, and consumer electronics, where reliable overvoltage protection is crucial. Supreme Components International ensures the authenticity and quality of this JSCJ (JCET) component.
