NOTES:
1.
TOLERANCE AND VOLTAGE DESIGNATION –
The JEDEC type numbers without a letter prior to the UR-1 suffix are +/-20% with guaranteed limits for only V
Z
, I
R
, and V
F
.
Units with “A” prior to the UR-1 suffix are +/-10% with guaranteed limits for V
Z
, I
R
, and V
F
. 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-1 suffix.
2.
ZENER VOLTAGE (V
Z
) MEASUREMENT –
Nominal zener voltage is measured with the device junction in thermal equilibrium with ambient temperature of 25
o
C.
3.
ZENER IMPEDANCE (Z
Z
) 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 (I
ZT
) is superimposed on I
ZT
.
4.
REVERSE CURRENT (I
R
) –
Reverse currents are guaranteed and are measured at V
R
as shown on the table.
5.
MAXIMUM REGULATOR CURRENT (I
ZM
) –
The maximum current shown is as shown in MIL-PRF-19500/437.
6.
MAXIMUM REGULATION FACTOR (
V
Z
) –
V
Z
is the maximum difference between V
Z
at I
ZT
and V
Z
at I
ZL
measured with the device junction in thermal equilibrium.
7.
PART NUMBER – These may be ordered as either 1N5518BUR-1 thru 1N5546BUR-1 or as MLL5518B-1 thru MLL5546B-1 part
numbers. For military types, use the 1NxxxUR-1 format and also include JAN, JANTX, or JANTXV prefix for desired screening
level, e.g. JANTX1N5518BUR-1, JANTXV1N5532BUR-1, JANTXV1N5534CUR-1, JANTXV1N5545DUR-1, etc.
