The Diptronics P4SMA300C is a Surface Mount Bidirectional Transient Voltage Suppressor (TVS) Diode designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a breakdown voltage of 300V, this TVS diode effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. Its bidirectional configuration provides symmetrical protection for AC and DC circuits. Supreme Components International is an authorised distributor of Diptronics, ensuring you receive genuine, high-quality components. The P4SMA300C is ideal for use in telecommunications equipment, industrial controls, consumer electronics, and other applications requiring robust transient voltage protection. Its surface mount package allows for easy integration into printed circuit boards, saving valuable board space.
