The CL04-12A High Voltage Rectifier Diode is a high-reliability silicon rectifier designed for medium-frequency and power-frequency high-voltage rectification applications. With a 12kV repetitive peak reverse voltage (VRRM) and 500mA average forward current, the CL04-12A provides stable high-voltage performance, low leakage current, and excellent surge capability for demanding industrial environments.
Compared with the standard CL04-12, the CL04-12A incorporates an additional 0.1A repetitive surge reverse current (IRSM) capability, improving transient tolerance and long-term reliability in applications with switching or pulse conditions.
Ideal for OEM manufacturers, industrial equipment suppliers, microwave oven manufacturers, electrostatic systems, and custom high-voltage power supply designers.
