Operating Temperature: to +175�C Storage Temperature: to +175�C Forward Voltage @ 200 mA: 1.5 Volts Maximum ELECTRICAL CHARACTERISTICS @ 25�C, unless otherwise speci�ed
METALLIZATION: Top: (Anode)......................Al Back: (Cathode)..............Au THICKNESS............25,000 � Min GOLD THICKNESS.......4,000 � Min CHIP THICKNESS.................10 Mils CIRCUIT LAYOUT DATA: For Zener operation, cathode must be operated positive with respect to anode. TOLERANCES: ALL Dimensions + 2 mils, Except Anode Pad Where Tolerance + 0.1 mils.
NOTE 1 Suffix "B" voltage range equals nominal Zener voltage + 5%. Suffix "A" equals 10%. No Suffix equals + 20%. Zener voltage is read using a pulse measurement, 10 milliseconds maximum. "C" suffix + 2% and "D" suffix = +1%. NOTE 2 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal 10% of lZT. NOTE 3 �VZ is the maximum difference between @ 1ZT and at 1ZL measured with the device junction in thermal equilibrium at an ambient temperature + 3�C.
