Notes 1. The zener voltage (VZ) of the B and B1 to B7 grades is tested for 40 ms after power ON. 2. The operation resistance (ZZ, ZZK) is tested by superimposing a micro AC on the standard current (IZ). Remark The B grade is a composition of the B1 to B7 grades. Any of the B1 to B7 voltage classifications are available for customers who request the B grade product.
