The SM4F10A-MS-Q1-H is a robust Transient Voltage Suppressor (TVS) Diode manufactured by FORMOSA MICROSEMI. This diode is specifically designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a power dissipation rating of 400W and a breakdown voltage of 10V, the SM4F10A-MS-Q1-H effectively clamps overvoltage events, preventing damage to downstream circuitry. Its DO-221AC (SMPC) surface-mount package allows for efficient heat dissipation and easy integration into printed circuit boards. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive genuine and high-quality products. This TVS diode is suitable for a wide range of applications, including automotive, industrial, and consumer electronics.
