ON Semiconductor guarantees the zener voltage when measured at 40 ms ±10 ms, 3/8″ from the diode body. And an ambient temperature
of 25°C (+8°C, -2°C)
The zener impedance is derived from 60 seconds AC voltage, which results when an AC current having an rms value equal to 10% of the
DC zener current (I
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or
equivalent sine wave pulse of 1/120 second duration superimposed on the test current, I
capability is as described in Figure 3 of the General Data sheet for Surmetic 30s.
