The P4SMAJ51A is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by DIOTEC. Supreme Components International is an authorised distributor of DIOTEC components, ensuring you receive genuine and reliable parts. This TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a standoff voltage of 51V and a peak pulse power dissipation of 400W, the P4SMAJ51A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its SMA package allows for easy and efficient surface mount assembly. This diode is suitable for a wide range of applications, including telecommunications, industrial control, and consumer electronics, where robust overvoltage protection is critical.
