The P4SMAJ51CA is a high-performance bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diotec. Supreme Components International is an authorised distributor of Diotec components. This TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a power dissipation rating of 400W and a breakdown voltage of 51V, the P4SMAJ51CA provides effective overvoltage protection. Its bidirectional configuration allows it to suppress voltage spikes in both directions, making it suitable for AC and DC applications. The SMA package enables easy surface mounting, saving valuable board space. This TVS diode is ideal for use in telecommunications equipment, industrial control systems, and consumer electronics.
