描述 Description

The popular 1N4728AP thru 1N4764AP series of 1.0-watt Zener’s provides voltage regulation in a selection from 3.3 to 100 volts in 5% tolerances with other tighter tolerances also available as identified by different suffix letters in the part number. These plastic encapsulated Zener’s are moisture classified as Level 1 with no dry pack required. They are also available in various military screening levels by adding a prefix identifier as described in the Features below. These plastic molded Zener’s with a P suffix provide a lower thermal resistance compared to the glass-body (G suffix) option for these same JEDEC part numbers. Both package options are available by Microchip in RoHS Compliant devices with an “e3” suffix. Microchip also offers numerous other Zener products to meet higher and lower power and test current applications.
