The type numbers shown above have a standard tolerance of ±5% on the nominal Zener voltage. Also available in 2% and 1%
tolerance, suffix C and D respectively. Vz is measured with the diode in thermal equilibrium in 25℃ still air.
2)
Zener impedance is derived by superimposing on IZT, a 60Hz rms a.c. current equal to 10% of IZT (25uA a.c.)
3)
Based upon 400 mW maximum power dissipation at 75℃ lead temperature, allowance has been made for the higher voltage
associated with operation at higher currents.
