TOLERANCE AND TYPE NUMBER DESIGNATION (V Z) The type numbers listed have a standard tolerance on the nominal zener voltage of ± 5%. 3. ZENER VOLTAGE (V Z) MEASUREMENT The zener voltage (V Z) is tested under pulse condition. The measured V Z is guaranteed to be within specification with device junction in thermal equilibrium. 4. ZENER IMPEDANCE (Z Z) DERIVATION Z ZT and Z Zk are 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 AC frequency = 60Hz. 5. TEMPERATURE COEFFICIENT (θ VZ) Test conditions for temperature coefficient are as follows: A. IZT = 7.5mA, T1 = 25℃, T2 = 125℃ (1N5221B through 1N5242B) B. IZT = Rated IZT , T1 = 25℃, T2= 125℃ (1N5243B through 1N5281B) Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature.
