Note 1: The JEDEC type number shown with an A suffix have a 5% tolerance on nominal zener voltage. No

suffix signifies a 10% tolerance, C signifies 2%, and D suffix signifies 1% tolerance.

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(I_ZTor I_ZK) is superimposed on I_ZTor I_ZK. Zener

impedance is measured at two points to insure a sharp knee on the breakdown curve and eliminate

unstable units.

3: The reverse surge current is measured at 25^oC ambient using a 1/2 square wave or equivalent sine

wave pulse 1/120 second duration superimposed on I_ZT.

4: Voltage measurements tobe performed 90 seconds after application of DC current.
