Note 1: The part numbers shown above have a Zener voltage tolerance of ±5% of the
nominal Zener voltage. VZ is measured with the device junction in thermal equilibrium
at an ambient temperature of 25° C ± 3° C.
Note 2: Based upon 400mW maximum power dissipation at 25° C lead temperature, allowance
has been made for the higher voltage associated with operation at higher currents.
