ELECTRICAL CHARACTERISTICS @ 25C Note 1 The JEDEC type numbers shown with no suffix have a +10% tolerance on nominal V,. Suffix A denotes a 5% tolerance. C denotes a +2% tolerance and D denotes a +1% tolerance. Note 2 Voltage measurement performed with the device junction in thermal equilibrium with lead temperature of 30C41C and 3/8" lead length. Note 3 The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the DC zener Current (I,,) is superimposed on la. Note 4 The maximum current shown is based on the maximum voltage of a 10.0% 1N746 type unit. For coser tolerance units 4 for any device may be increased and Is limited by the derating curve.
