1. TOLERANCE AND TYPE NUMBER DESIGNATION
The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.

2. ZENER VOLTAGE (V
ON Semiconductor guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (T
3/8″ from the diode body.

3. ZENER IMPEDANCE (Z
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

4. SURGE 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.
