Zener voltage tolerance on "A" suffix is +5%.
No Suffix denotes + 10% tolerance, "C" suffix denotes + 2% tollerance and "D" suffix denotes + 1% tolerance.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C.
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.
c.
current equal to 10% of 1ZT
