10 Mils CIRCUIT LAYOUT DATA: For Zener operation, cathode must be operated positive with respect to anode.
TOLERANCES: ALL Dimensions + 2 mils NOTE 1 NOTE 2 NOTE 3 Zener voltage range equals nominal voltage +5% for “A” Suffix types.
No Suffix denotes + 10%.
"C" suffix = + 2% and "D" suffix = + 1%.
Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.
c.
current equal to 10% of 1ZT.
