DESCRIPTION
APPEARANCE
The 1N5518 thru 1N5546 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.
These glass axial-leaded DO-35 Zeners are also available with an internal-
metallurgical-bond option by adding a “-1” suffix. This type of bonded Zener
package construction is 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.
