The DIOTEC P4SMAJ20A 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 diode features a standoff voltage of 20V and a peak pulse power dissipation of 400W. Its SMA package allows for easy integration into printed circuit boards. As an authorized distributor of DIOTEC components, Supreme Components International guarantees the authenticity and quality of the P4SMAJ20A. This TVS diode is commonly used in telecommunications, industrial control, and consumer electronics applications to enhance system reliability and prevent damage from voltage surges. Its fast response time and low clamping voltage make it an excellent choice for protecting sensitive circuitry.
