Notes :

(1) The type number listed have a standard tolerance on the nominal zener voltage of ±5%,

altered the fourth number of type from " 5 " for ±5% tolerance to be " 0 " for ±10% tolerance.

(2) The revese surge current is a non-repetitive, 8.3ms pulse width square wave or equivalent sine-wave superimposed

(3) " SZ " will be omitted in marking on the diode.
