The P4SMA47CA is a Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of JSCJ components. 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 reverse standoff voltage of 47V and a peak pulse power dissipation of 400W. The P4SMA47CA is available in a compact DO-214AC (SMA) surface-mount package, making it suitable for high-density circuit board applications. Its fast response time and low clamping voltage ensure effective protection against overvoltage events. This TVS diode is commonly used in telecommunications equipment, industrial controls, and consumer electronics to enhance system reliability and prevent damage from transient voltages.
