The SEMIKRON HSK E 14000/6300‑0,4 is a high-voltage, ceramic-tube rectifier diode designed for circuit applications requiring avalanche operation and high repetitive peak reverse voltage. Encapsulated in a hermetic glass-ceramic tube, it can be fastened via threaded or soldered connections and is suitable for operation in both air and oil environments. Primarily used in high-voltage power supplies, laser systems, and measurement or medical equipment.
