The SM4F30CA-MS-Q1-H is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. This diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a breakdown voltage of 30V and a peak pulse power dissipation, it provides excellent clamping characteristics. The SM4F30CA-MS-Q1-H is housed in a compact DO-214AA package, making it suitable for space-constrained applications. It is commonly used in automotive electronics, industrial control systems, and telecommunications equipment. As an authorized distributor of FORMOSA MICROSEMI, Supreme Components International guarantees the authenticity and quality of this product. This TVS diode offers a reliable and cost-effective solution for overvoltage protection.
