TOLERANCE AND VOLTAGE DESIGNATION The type numbers listed have a standard tolerance on the nominal zener voltage of 5%. 3. ZENER VOLTAGE (VZ) MEASUREMENT The zener voltage (VZ) is tested under pulse condition. The measured VZ is guaranteed to be within specification with device junction in thermal equilibrium. 4. ZENER IMPEDANCE (ZZ) DERIVATION ZZT 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 AC frequency = 60Hz. 5. MAXIMUM ZENER CURRENT RATINGS (IZM) Values shown are based on the JEDEC rating of 400mW where the actual zener voltage (VZ) is known at the operation point, the zener current may be increased and is limited by the derating curve.
