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
TOLERANCES: ALL Dimensions

Tolerance is + 0.1 mils.
