NOTE 1. Tolerance Designation - The type numbers
shown have tolerance designations as follows:
MLL4370 series: ± 10%, suffix A for ± 5% units.
MLL746 series: ± 10%, suffix A for ± 5% units.
MLL957 series:
suffix A for ± 10% units,
suffix B for ± 5% units.
NOTE 2. Special Selectionst Available Include: 1. Nominal zener voltages between those shown. 2. Two or more units for series connection with spec-
ified tolerance on total voltage. Series matched sets make zener voltages in excess of 200 volts possible as well as providing lower temperature coefficients, lower dynamic impedance and greater power handling ability.
3. Nominal voltages at non-standard test currents.
NOTE 3. Zener Voltage (VZ) Measurement - Nominal zener voltage is measured with the device junction in thermal equilibrium a.
