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-204AL

*JEDEC Registered Data

NOTES:

1. 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_ZTor I_ZK) is superimposed on I_ZTor I_ZK. Zener impedance is measured at two points to ensure a sharp knee on the

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 25^oC ambient using a ½ square wave or equivalent sine wave pulse 1/120 second duration

superimposed on I_ZT.

4. Zener voltage (V_Z) is measured at T_L= 25ºC (+8, -2ºC) and 90 seconds after application of dc current.
