1N4728AP thru 1N4764AP,e3 (PLASTIC)

Silicon 1 Watt Zener Diodes

S C O T T S D A L E D I V I S I O N

DESCRIPTION

APPEARANCE

The popular 1N4728AP thru 1N4764AP series of 1.0 watt Zeners 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 Zeners 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 Zeners 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

Microsemi in RoHS Compliant devices with an “e3” suffix. Microsemi also

offers numerous other Zener products to meet higher and lower power and

test current applications.

DO-41 or

DO-204AL

(Plastic)
