IN5518BUR-1 thru 1N5546BUR-1  
(or MLL5518B-1 thru MLL5546B-1)  
Low Voltage Surface Mount  
500 mW Avalanche Diodes

DESCRIPTION  
APPEARANCE  
The 1N5518BUR-1 thru 1N5546BUR-1 series of 0.5 watt glass surface  
mount Zener voltage regulators provides a selection from 3.3 to 33 volts in  
standard 5% tolerances as well as tighter tolerances identified by different  
suffix letters on the part number. These have an internal-metallurgical-bond  
option as identified by the “–1” suffix. This internally bonded Zener package  
construction is also in JAN, JANTX, and JANTXV military qualifications.  
Microsemi also offers numerous other Zener products to meet higher and  
lower power applications.  
DO-213AA

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 VZ, IR, and VF.  
Units with “A” prior to the UR-1 suffix 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-1 suffix.  
2. ZENER VOLTAGE (VZ) MEASUREMENT –  
Nominal zener voltage is measured with the device junction in thermal equilibrium with ambient temperature of 25oC.  
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 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.
