Notes 1.
The zener voltage (V
Z
) of the B and B1 to B3 grades is tested for 40 ms after power ON.
2.
The dynamic impedance (Z
Z
) is tested by superimposing a micro AC on the standard current (I
Z
).
3.
The B grade of the RD2.0F to RD39F is a composition of the B1 to B3 grades. Any of the B1, B2, and B3
voltage classifications are available for customers who request the B grade product.
