The Zener Voltage is measured under pulse conditions so that TJ is no more than 2oC greater than TA. 2. Part numbers have max / min Zener Voltage as listed. Tolerance of 2% is designated by a “B” in place of the “C”, and 1% by an “A”. 3. The Zener Impedance is measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 1.0kHz. Electrical Characteristics @ 25 O C.
