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 cps, rms
ac current equal to 10% I
ZT
(2 mA ac)
4) Allowance has been made for the increase in V
Z
due to Z
Z
and for
the increase in junction temperature as the unit approaches
thermal equilibrium at the power dissipation of 400mW.
