T4-LDS-0228-1, Rev. 1 (111898) (c)2011 Microsemi Corporation Page 3 of 5 1N5985BUR-1 thru 1N6031BUR-1 NOTES: 1. Zener impedance is derived from the 1 kHz ac voltage that results when an ac current having an rms value equal to 10% of dc Zener current (I ZT or I ZK ) is superimposed on I ZT or I ZK . See "MicroNote 202" for dynamic impedance variation with other operating currents. 2. Voltage measurements to be performed 20 seconds after application of the dc test current. 3. The maximum Zener current I ZM shown is for the nominal voltages. The following formula can be used to determine the worst case current for any tolerance device: I ZM = P VZM Where V ZM is the high end of the voltage tolerance specified and P is the rated power of the device.
