The DIOTEC P4SMAJ54A is a surface-mount Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). This 54V, 400W TVS diode is specifically engineered to clamp transient voltages to a safe level, preventing damage to downstream components. Its DO-214AC (SMA) package allows for efficient heat dissipation and easy integration into printed circuit boards. The P4SMAJ54A offers fast response time, high surge capability, and low clamping voltage, making it suitable for a wide range of applications, including automotive, industrial, and consumer electronics. As an authorized distributor of DIOTEC components, Supreme Components International guarantees the authenticity and quality of this product.
