Zener voltage is read using a pulse measurement, 10 milliseconds maximum. "C" suffix = + 2% tolerance and "D" suffix = + 1% tolerance. NOTE 2 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal to 10% of lZT. DESIGN DATA METALLIZATION: Top: (Anode)......................Al Back: (Cathode)............. ..Au CIRCUIT LAYOUT DATA: For Zener operation, cathode must be operated positive with respect to anode.
