SM4F18A-MS-Q1-H Datasheet
Product Description
The SM4F18A-MS-Q1-H is a high-performance Transient Voltage Suppressor (TVS) Diode manufactured by FORMOSA MICROSEMI. This unidirectional diode is 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 reverse standoff voltage of 18V, the SM4F18A-MS-Q1-H provides reliable overvoltage protection. 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, guaranteeing the authenticity and quality of this TVS diode. This component is ideal for automotive, industrial, and consumer electronics applications requiring robust surge protection.
