The P4SMAJ28CA is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by Diotec. This bidirectional TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a power dissipation of 400W and a standoff voltage of 28V, the P4SMAJ28CA provides robust protection in a small SMA package. Its bidirectional clamping capability makes it suitable for AC and DC applications. Supreme Components International is an authorized distributor of Diotec, guaranteeing the authenticity and quality of this component. This diode is commonly used in telecommunications, industrial control, and consumer electronics applications to enhance system reliability and prevent costly damage from voltage surges.
