Note:
1) Tested with pulses t p
= 20ms
2) Valid provided that leads are kept at ambient temperature at a
distance of 8mm from case.
3) Zener impedance derived by superimposing on IZT, a 60 Hz, rms
ac current equal to 10% IZT (2 mA ac)
4) Allowance has been made for the increase in VZdue to ZZand for
the increase in junction temperature as the unit approaches
thermal equilibrium at the power dissipation of 400mW.
