DESIGN DATA
METALLIZATION:
Top: C (Cathode) .............Al
A (Anode) ................Al
Back:.................................Au
AL THICKNESS.......25,000 Å Min
GOLD THICKNESS...4,000 Å Min
CHIP THICKNESS.............10 Mils
NOTE 1
Zener impedance is derived by superimposing on lZT @ 60Hz rms a.c. current equal
to 10% of lZT.
NOTE 2
The maximum allowable change observed over the entire temperature range
i.e.,the diode voltage will not exceed the specified mV at any discrete
temperature between the established limits, per JEDEC standard No. 5.
CIRCUIT LAYOUT DATA:
Backside must be electrically
isolated.
Backside is not cathode.
For Zener operation cathode must
be operated positive with respect
to anode.
TOLERANCES: ALL
