1. TOLERANCE AND TYPE NUMBER DESIGNATION Tolerance designation � device tolerance of �5% are indicated a "5" suffix. 2. ZENER VOLTAGE (VZ) MEASUREMENT ON Semiconductor guarantees the zener voltage when measured ms �10 ms, 3/8 from the diode body. And an ambient temperature �2�C) 3. ZENER IMPEDANCE (ZZ) DERIVATION The zener impedance is derived from 60 seconds AC voltage, which results when an AC current having an rms value equal 10% of the DC zener current (IZT or IZK) is superimposed on IZT or IZK. 4. SURGE CURRENT (IR) NON�REPETITIVE 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, IZT, per JEDEC standards. However, actual device capability is as described in Figure 3 of the General Data sheet for Surmetic 30s. *Not Available in the 6000/Tape & Reel. 5 PD, STEADY STATE POWER DISSIPATION (WATTS) = 1/8
