DESCRIPTION
APPEARANCE
DO-7
The 1N5518B thru 1N5546B series of 0.5 watt 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. The
DO-7 packaging offers a “straight-through” soldered internal connection with
a larger active die element than otherwise provided in the smaller DO-35
package if needed. This DO-7 package option is also available in JAN,
JANTX, and JANTXV military qualifications to MIL-PRF-19500/437.
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 are +/-20% with guaranteed limits for only VZ, IR, and VF. Units with A 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%.
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 LEAKAGE CURRENT (IR) –
.
Reverse leakage 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.

CIRCUIT AND GRAPHS
Noise density, (ND) is specified in microvolts rms per
square-root-Hertz (µV/ √Hz). Actual measurement is
performed using a 1 kHz to 3 kHz frequency bandpass
filter with a constant Zener test current (IZT) at 25oC
ambient temperature.
