Note 1:
1N3993-1N4000 series: suffix A indicates +/-5% tolerance, no suffix indicates +/-10% tolerance.
1N2970-1N3015 series: suffix B indicates +/-5% tolerance, suffix A indicates +/-10% no suffix indicates +/-20% tolerance, suffix C indicates +/-2% tolerance, suffix D
indicates +/-1% tolerance.
Note 2: The electrical characteristics are measured after allowing the device to stabilize for 90 seconds with 30°C base temperature
Note 3: 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 the voltmeter to avoid errors resulting from low level noise signals.
Note 4: These values of IZM may be exceeded in the case of the 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.
