KIV 5D Component Identification – What Type of Electronic Part Is This?

The component marked "KIV 5D" is identified as a SIDAC, a bi-directional voltage-triggered switch belonging to the thyristor family. It is similar to a DIAC but less common, with higher breakover voltages and greater current handling capacity. Initial assumptions suggested it might be a diode or a high voltage, high current Schottky diode, but further clarification confirmed the correct part number as "K1V-5D," indicating a SIDAC device. Testing with a multimeter diode test can help verify its condition. For replacement or application purposes, providing schematic context, voltage, current, and usage details (e.g., high frequency switching or mains) is recommended.
