Nominal zener voltage is measured with the device junction in thermal equilibrium at the lead temperature of 30C +1C and 3/8” lead length. Note 2. Test conditions for temperature coefficient are as follows: a.Izt = 7.5mA, T1 = +25C, T2 = +125C (1N5223B thru 1N5242B) b.Izt = Rated Izt, T1 = +25C, T2 = +125C (1N5243B thru 1N5271B) Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature. Note 3. ZZT an ZZK are measured by dividing the AC voltage drop across the device by the AC current applied. The specific limits are for IZ(AC) = 0.1 IZ(DC) with the AC frequency = 60Hz.
