These plastic encapsulated Zeners are moisture (Plastic) 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.

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 ZT ZK ZT ZK breakdown curve and eliminate unstable units. See MicroNote 202 for zener impedance variation with different operating currents. o 3. The reverse surge current is measured at 25 C ambient using a square wave or equivalent sine wave pulse 1/120 second duration superimposed on I . ZT 4. Zener voltage (V ) is measured at T = 25C (+8, -2C) and 90 seconds after application of dc current. Z L Copyright 2005 Microsemi Page 2 10-18-2005 REV C Scottsdale Division 8700 E. Thomas Rd.
