Product Q&A

Q:What is the difference between the red and black wire diodes?

The red wire diode is the positive polarity type, while the black wire is the negative polarity type. Both are needed to form a full rectifier circuit in the generator rotor.

Q:Can this diode replace the original ZX40A model?

Yes, this ZX40A diode is a direct replacement for the standard 40A rotating rectifier diode used in most brushless generators, with the same specifications and mounting size.

Q:What is the working voltage and current rating?

It is rated at 40A average forward current and 1200V reverse voltage, suitable for most common brushless generator excitation systems.
