A surface mount diode is a semiconductor device mounted onto the surface of an electronic device's substrate using surface mount technology (SMT).
Compared to traditional through-hole diodes, surface mount diodes offer advantages such as smaller size, lighter weight, and enhanced suitability for automated assembly processes. These characteristics have led to widespread adoption of various electronic devices in recent years. The operational principle relies on the semiconductor's PN junction structure. Application of voltage to this junction enables functions such as rectification, detection, frequency conversion, and amplification.
Surface mount diodes find extensive use in applications ranging from mobile phones, computers, and digital cameras to automobiles and industrial equipment. Their compactness, lightweight nature, and suitability for high-density mounting make them ideal for modern electronics. Structurally, they consist of a semiconductor chip, electrodes, and protective packaging.
