Description
High Current (500mA), Fast Recovery, Multiple Package Options – Engineered for High Power High Voltage Systems
The CL-500mA Series from HVRTION is a high‑performance family of fast recovery high voltage diodes designed for applications requiring high forward current (500mA), fast switching (Trr down to 100ns), and excellent surge tolerance (up to 30A). Covering voltages from 8KV to 20KV, the CL-500mA series delivers reliable rectification for high power X‑ray generators, industrial lasers, capacitor charging systems, and high frequency power supplies. Four models offer flexibility in package size and electrical characteristics to match different design requirements.
