1N5518B thru 1N5546B-1
Low Voltage Avalanche
500 mW Zener Diodes DO-35
Qualified per MIL-PRF-19500/437
DESCRIPTION
The 1N5518 thru 1N5546 series of 0.5 watt axial-leaded glass Zener Voltage Regulators
provides a selection from 3.3 to 33 volts with tolerances ranging from plus/minus 1% to 20%.
The standard tolerance is plus/minus 5% with the B suffix unless ordered otherwise. These
axial-leaded glass DO-35 Zeners are also available with an internal metallurgical bond option.
This type of bonded Zener package construction is also available in JAN, JANTX, and
JANTXV military qualifications. Microsemi also offers numerous other Zener products to meet
higher and lower power applications.
