The JEDEC type numbers shown with an A suffix have a 5% tolerance on nominal zener voltage. No suffix signifies a 10% tolerance,
C signifies 2%, and D signifies 1% tolerance. Also add a P suffix for designating plastic construction, e.g. 1N4764AP (G suffix
designates glass body options described by separate data sheet).
The Zener impedance is derived from the 60 Hz ac voltage that results when an ac current having an rms value equal to 10% of the dc
Zener current (I
breakdown curve and eliminate unstable units. See MicroNote 202 for zener impedance variation with different operating currents.
The reverse surge current is measured at 25
