Meter Star CL04-12 Microwave High Voltage Diode 2 Pack, 12KV 500mA Insulated Rectifier for Oven Repair

Microwave oven high-voltage circuit problems may require a correctly rated replacement diode to restore proper rectification in the power supply system. The Meter Star CL04-12 microwave high voltage diode is designed for repair and maintenance use in compatible microwave ovens with matching electrical specifications.

This insulated rectifier diode is rated 12KV and 500mA. It is compatible with replacement part numbers WB27X10597, W10492276, T4512, 4512, CL4512, and CL04-12. It is also listed for compatible GE, LG, Amana, Electrolux, Kenmore, Maytag, and Whirlpool microwave ovens where the original diode rating, connector size, and part specification match.

For electrical performance, the diode uses a fast recovery rectifier design with low leakage current and high surge capability. Its epoxy resin molded body, compact encapsulation, and polyimide passivation support use in demanding microwave oven high-voltage environments.

The female terminal includes heat shrink tubing for added insulation. Terminal sizing includes a 4.2mm male terminal diameter and a 1/4 inch standard female terminal for connection with compatible microwave wiring.

The operating temperature range is -40°C to +150°C. The package includes 2 CL04-12 insulated microwave diodes, giving buyers one replacement part and one spare when needed.

For testing and polarity verification, use an analog multimeter with a 9V DC battery, because the diode gate voltage requirement may be higher than the 3V DC typically supplied by many digital multimeters. Always confirm part number, electrical rating, connector size, and microwave model compatibility before installation.
