The zener voltage (VZ) is tested under pulse condition of 1mS. 2. The device numCers listed have a standard tolerance on the nominal zener voltage of ±2%. 3. The zener impedance is derived from the 60-cycle 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 to IZT or IZK. 4. For detailed information on price, availaCility and delivery of nominal zener voltages Cetween the voltages shown and tighter voltage tolerances, contact your nearest Tak Cheong Electronics representative. |
