If tighter tolerance is required, consult factory. o The electrical characteristics are measured after allowing the device to stabilize for 90 seconds with 30 C Base temperature. The zener impedance (ZZT) is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed on IZT or IZK. When making zener impedance measurements at the IZK test point, it may be necessary to insert a 60 Hz band pass filter between the diode and voltmeter to avoid errors resulting from low level noise signals. A curve showing the variation of zener impedance vs. zener current for three representative types is shown in Figures 2 and 3. Also see Microsemi MicroNote 202. These values of IZM may be exceeded in the case of individual diodes. The values shown are calculated for the worst case that is a unit of +/-5% tolerance at the high voltage end of its tolerance range. Allowance has also been made for the rise in zener voltage above VZT, which results from zener impedance and the increase in junction temperature as power dissipation approaches 10 watts. 1N2970 thru 1N3015B and 1N3993 thru 1N4000A 10 WATT ZENER DIODES SCOTTSDALE DIVISION WWW .
