TOLERANCE AND VOLTAGE DESIGNATION The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%. 3. Z ENER 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. Z ENER IMPEDANCE (Z Z) DERIVATION ZZT and ZZK 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. M AXIMUM ZENER CURRENT RAT INGS (IZM) Values shown are based on the JEDEC rating of 400mW where the actual zener voltage (V Z) is known at the operation point, the zener current may be increas ed and is limited by the derating curve.
