1N4728AP thru 1N4764AP,e3 (PLASTIC) Silicon 1 Watt Zener Diodes SCOTTSDALE DIVISION DESCRIPTION APPEARANCE W The popular 1N4728AP thru 1N4764AP series of 1.0 watt Zeners provides W DO-41 or W 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 DO-204AL M. in the part number. These plastic encapsulated Zeners are moisture (Plastic) ic r classified as Level 1 with no dry pack required. They are also available in o s various military screening levels by adding a prefix identifier as described in e the Features below. These plastic molded Zeners with a P suffix provide a m lower thermal resistance compared to the glass-body (G suffix) option for i . these same JEDEC part numbers. Both package options are available by C O Microsemi in RoHS Compliant devices with an “e3” suffix. Microsemi also M offers numerous other Zener products to meet higher and lower power and test current applications.

The JEDEC type numbers shown with an A suffix have a 5% tolerance on nominal zener voltage. No suffix signifies a 10% tolerance, C signifies 2%, and D signifies 1% tolerance. Also add a P suffix for designating plastic construction, e.g. 1N4764AP (G suffix designates glass body options described by separate data sheet). 2. The Zener impedance is derived from the 60 Hz ac voltage that results when an ac current having an rms value equal to 10% of the dc Zener current (I or I ) is superimposed on I or I . Zener impedance is measured at two points to ensure a sharp knee on the 1 ZT ZK ZT ZK N breakdown curve and eliminate unstable units. See MicroNote 202 for zener impedance variation with different operating currents. 3. The reverse surge current is measured at 25oC ambient using a ½ square wave or equivalent sine wave pulse 1/120 second duration 47 superimposed on I . 2 ZT 8 4. Zener voltage (VZ) is measured at TL = 25ºC (+8, -2ºC) and 90 seconds after application of dc current.
