DESIGN DATA
METALLIZATION:
Top: (Anode)................ ....Al
Back: (Cathode)............. Au
AL THICKNESS...... .....25,000 Å Min
GOLD THICKNESS........4,000 Å 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
NOTE 1 Zener voltage range equals nominal Zener voltage + 5% for “A” Suffix. No Suffix
denotes + 10%. 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 to 10% of lZT.
