mpz5 - 16 series, mpz5 - 32 series, mpz5 - 180 series (continued) note t: nominal operating voltage is defined as normal input voltage to device for non - operating condition. if non - sinusoidal wave or dc input is present, peak voltage input values v op(pk) shoul d be used to select device type. note 2: the maximum device clamping factor cf is a ratio of vz measured at iz (pulse) given in the electrical characteristics table divided by vz measured at izt under steady state conditions. this value guarantees the sha rpness of the voltage breakdown of individual devices. figure 2 demonstrates the typical sharpness of the breakdown, and indicates the voltage regulation over a wide range of currents. ?vz = vz @ iz(pulse) - vz @ izt
