The P4SMAJ78CA from Diotec is a Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a reverse standoff voltage of 78V and a power dissipation of 400W, this diode effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its 5% voltage tolerance ensures reliable performance. The P4SMAJ78CA is housed in a compact DO-214AC package, making it suitable for a wide range of applications. Supreme Components International is an authorised distributor of Diotec, guaranteeing the authenticity and quality of this TVS diode. This robust component is ideal for automotive, industrial, and consumer electronics applications requiring reliable overvoltage protection.
