Tolerance and type number designation the type numbers listed indicate a tolerance of 5% 2. Zener voltage (Vz) measurement: Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature 25°C 3. Zener impedance (Zz) derivation : ZZT and ZZK are measured by dividing the AC voltage drop across the device by the AC current applied. 4. The specified limits are for Iz(AC) = 0.1 Iz(DC) with the AC frequency = 60Hz 2 Version: M2102 1SMB5926 – 1SMB5956 Taiwan Semiconductor ORDERING INFORMATION ORDERING CODE(1) PACKAGE PACKING 1SMB59x DO-214AA (SMB) 3,000 / Tape & Reel Notes: 1.
