No suffix signifies 10% tolerance, A signifies 5% tolerance, C signifies 2% tolerance, and D signifies 1% tolerance.
10% of the DC zener current (Izt or Izk) is superimposed on Izt or Izk. Zener impedance is measured at two points to insure
a sharp knee on the breakdown curve and eliminate unstable units.
