CIRCUIT LAYOUT DATA:
For Zener operation, cathode
must be operated positive with
respect to anode.
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 to 10% of lZT.
BACKSIDE IS CATHODE
DESIGN DATA
METALLIZATION:
Top: (Anode)................ ......Al
Back: (Cathode)............ ...Au
AL THICKNESS............25,000 Å Min
CHIP THICKNESS.............. ....10 Mils
TOLERANCES: ALL Dimensions
+ 2 mils, Except Anode Pad Where
Tolerance is + 0.1 mils.
NOTE 3 ∆VZ is the maximum difference between VZ @ 1ZT and VZ at 1ZL measured
with the device junction in thermal equilibrium at an ambient temperature of
+25° + 3°C.
