* Stud Temperature = +75
°C
Note 1. The NTE type 10W Zener Diodes listed have Anode (Standard Polarity) connected to stud.
Add suffix letter “K” to the device number for Cathode (Reverse Polarity) connected to stud
(i. e. NTE5174AK).
Note 2. The electrical characteristics are measured after allowing the device to stabilize for 90 se-
conds with +30
°C base temperature.
Note 3. The zener impedance (Zzt) is derived from the 60Hz AC voltage, which results when an AC
current having an RMS value equal to 10% of the DC zener current (IZT or IZK) is superim-
posed on IZT or IZK. When making zener impedance measurements at the IZK test point, it
may be necessary to insert a 60Hz band pass filter between the diode and voltmeter to avoid
errors resulting from low level noise signals.
Note 4. These values of IZM may be exceeded in the case of individual diodes. The values shown
are calculated for the worst case which is a unit of
±5% tolerance at the high voltage and 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 dis-
sipation approaches 10 watts.
