1N5728B thru 1N5757B-1 DO-35
Axial-Leaded 500 mW Zener Diodes
SCOTTSDALE DIVISION
DESCRIPTION
The 1N5728 thru 1N5757 series of 0.5 watt Zener Voltage Regulators
provides a selection from 4.7 to 75 volts in standard 5% tolerances as well
as tighter tolerances identified by a “C” or “D” suffix letter on the part
number. These glass axial-leaded DO-35 Zeners are also available with an
internal-metallurgical-bond option by adding a “-1” suffix. Microsemi also
offers numerous other Zener products to meet higher and lower power
applications.

Devices listed have a +/-5% voltage tolerance on nominal Vz with a B suffix. An A suffix is +/-10% and no suffix is +/-20%.
Suffix C denotes a +/-2% tolerance and suffix D denotes a +/-1% tolerance.
All static parameters measured under pulsed conditions, tp = 300
µs.
Dynamic Impedance is derived by measuring the ac voltage when superimposing an ac rms current of 0.2 mA at 1000 Hz on
to the dc level of I
