DESCRIPTION

APPEARANCE

The 1N5518BUR thru 1N5546BUR 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 are also available with an internal-

metallurgical-bond option by adding a “-1” suffix (see separate data sheet)

including JAN, JANTX, and JANTXV military qualifications. Microsemi also

offers numerous other Zener products to meet higher and lower power

applications.

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 V_Z, I_R, and V_F.

Units with A suffix prior to the UR 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.

2. ZENER VOLTAGE (V_Z) MEASUREMENT –

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

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_Ras 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_Zis the maximum difference between V_Zat I_ZTand V_Zat I_ZLmeasured 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.
