NOTE 1 The JEDEC type num-
bers shown have a 5% toler-
ance on nominal zener volt-
age. No suffix signifies a 10%
tolerance, C signifies 2%, and
D signifies 1 % tolerance.
NOTE 2 The Zener impedance
is derived from the 60 Hz ac
voltage,which results when an
ac current having an rms value
equal to 10% of the DC Zener
current (IZTor IZK)'* superim-
posed on l/r or IZK . Zener im-
pedance is measured at two
points to insure a sharp knee
on the breakdown curve and
eliminate unstable units.
NOTE 3 The zener surge cur-
rent is measured at 25°C ambi-
ent using a 1/2 square wave or
equivalent sine wave pulse
1/120 second duration super-
imposed orr IZT .
NOTE 4 Voltage measurements
to be performed 90 seconds
after application of DC current.
