NOTE 1 Zener voltage range equals nominal voltage +5% for “A” Suffix types. No Suffix denotes +10%. "C" suffix = +2% and "D" suffix = +1%. NOTE 2 Zener voltage is read using a pulse measurement, 10 milliseconds maximum. NOTE 3 Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT. MAXIMUM RATINGS Operating Temperature: -65°C to +175°C Storage Temperature: -65°C to +175°C Forward Voltage @ 200mA: 1.5 volts maximum Backside is Cathode FIGURE 1 DESIGN DATA METALLIZATION: GOLD THICKNESS ...4,000 Å Min CIRCUIT LAYOUT DATA: For Zener operation, cathode must be operated positive with respect to anode.
