Diode Arrays FAQ

What is the maximum non-repetitive peak surge current?

The maximum non-repetitive peak surge current is 150A when applied at rated load conditions on a half-wave, single-phase, 60Hz basis.

Does the device include electrostatic discharge protection?

Yes, the device offers ESD protection capabilities exceeding 400V via the machine model and greater than 8000V via the human body model.

What is the typical capacitance value at zero bias?

The datasheet provides a graph illustrating capacitance versus reverse voltage but does not specify a single fixed capacitance value; capacitance varies with the applied reverse voltage.
