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 I_ZT, a 60 Hz, rms

ac current equal to 10% I_ZT(2 mA ac)

4) Allowance has been made for the increase in V due to Z and for

the increase in junction temperature as the unit approaches

thermal equilibrium at the power dissipation of 400mW.
