NOTES:
1.
TOLERANCE AND VOLTAGE DESIGNATION –
The JEDEC type numbers shown without a suffix letter prior to the UR are +/-20% with guaranteed limits for only VZ, IR, and VF.
Units with A suffix prior to the UR are +/-10% with guaranteed limits for VZ, IR, and VF. Units with guaranteed limits for all six
parameters are indicated by a B suffix for +/-5.0% units, C suffix for +/-2.0% and D suffix for +/-1.0% prior to the UR.
2.
ZENER VOLTAGE (VZ) MEASUREMENT –
Nominal zener voltage is measured with the device junction in thermal equilibrium with ambient temperature of 25
oC.
3.
ZENER IMPEDANCE (ZZ) MEASUREMENT –
The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10%
of the dc zener current (IZT) is superimposed on IZT.
4.
REVERSE CURRENT (IR) –
Reverse currents are guaranteed and are measured at VR as shown on the table.
5.
MAXIMUM REGULATOR CURRENT (IZM) –
The maximum current shown is as shown in MIL-PRF-19500/437.
6.
MAXIMUM REGULATION FACTOR (
∆VZ) –
∆VZ is the maximum difference between VZ at IZT and VZ at IZL measured with the device junction in thermal equilibrium.
7.
PART NUMBER –
These may be ordered as either 1N5518UR thru 1N5546UR or as MLL5518 thru MLL5546 part numbers. For JAN, JANTX,
or JANTXV military types, see separate data sheet for the 1N5518UR-1 thru 1N5546UR-1 part numbers.
