The P4SMASF600A-Q1-H is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by Formosa Microsemi. Supreme Components International is an authorised distributor of Formosa Microsemi components, ensuring you receive only genuine and high-quality products. This TVS diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. It features a standoff voltage of 600V and a peak pulse power dissipation of 400W. The P4SMASF600A-Q1-H comes in a surface-mount SMA package, making it suitable for automated assembly and high-density circuit board designs. Its fast response time and low clamping voltage provide excellent protection against overvoltage events. Ideal for automotive, industrial, and consumer electronics applications where reliable transient voltage protection is critical.
