r MLL5518B-1 thru MLL5546B-1)

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.

IMPORTANT:

• Surface mount equivalent to JEDEC registered

• Internal metallurgical bond with the “-1” suffix

• Also available in JAN, JANTX, and JANTXV

• Nonbonded types also available without the “-1”

• DO-7 or DO-35 glass body axial-leaded Zener

• Operating and Storage temperature: -65

• Thermal Resistance: 100

• Steady-State Power: 0.5 watts at end cap

• Forward voltage @200 mA: 1.1 volts

• Solder Temperatures: 260

ZZT @ I

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 Units with “A” prior to the UR-1 suffix are +/-10% with guaranteed limits for V 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

) MEASUREMENT –

Nominal zener voltage is measured with the device junction in thermal equilibrium with ambient temperature of 25

3. ZENER IMPEDANCE (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

) is superimposed on IZT.

4. REVERSE CURRENT (IR) –

Reverse currents are guaranteed and are measured at V

5. MAXIMUM REGULATOR CURRENT (I The maximum current shown is as shown in MIL-PRF-19500/437.

6. MAXIMUM REGULATION FACTOR (∆V

∆

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.
