Note:
1. The type numers shown with an suffix have a 5tolerance on nominal zener voltage. No suffix signifies a 10%
tolerance, C siifies 2%, and D sinifies 1% tolerane.
2. The Zener impence is derived froth60 HZ ac voage ,which results when an ac current having an rms value equal to
0% of the dc Zeer current (IZT or IZK ) is superimposed on IZT or IZK. Zener impedance is measured at two points to insure a
sarp knee on the eakdown curve and eliminate unstable units.
3. Threverse surge crent is measured at 25°C ambient using a 1/2 square wave or equivalent sine wave pulse 1/120 second
duron superimposeon IZT.
4. Vtae at thermal equilrium or 90seconds after application of dc current.
