Designer's Data for "Worst Case" Conditions
The Designer's Data sheets permit the design of most circuits
entirely from the information presented. Limit curves - representing
boundaries on device characteristics - are given to facilitate
"worst case" design.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
Tolerance Designation
The type numbers shown have tolerance designations
as follows:
1N4370 series: ±10%, suffix A for ±5% units.
1N746 series: ± 10%, suffix A for ±5% units.
1N957 series:
suffix A for ± 10% units,
suffix B for ±5% units.
Voltage Designation
To designate units with zener voltages other than those
listed, the Motorola type number should be modified as
shown below. Unless otherwise specified, the electrical
characteristics other than the nominal voltage (Vz) and
test voltage for leakage current will conform to the
characteristics of the next higher voltage type shown
in the table.

Matched Sets for Closer Tolerances or Higher Voltages
Series matched sets make zener voltages in excess of
100 volts or tolerances of less than 5% possible as well
as providing lower temperature coefficients,lower dynamic
impedance and greater power handling ability.
For Matched Sets or other special circuit requirements,
contact your Motorola Sales Representative.
