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. Electrical Characteristics (Cont’d): (TC = +25C, unless otherwise specified) Maximum Dynamic Impedance (Note 3) Zener Test Current (Izt) Zzt @ Izt Zzk @ 0.25mA (Izk) Volts mA Ohms Ohms A 1N5231B 5.1 20 17 1600 5 2.0 0.030 1N5232B 5.6 20 11 1600 5 3.0 +0.038 1N5233B 6.0 20 7 1600 5 3.5 +0.038 1N5234B 6.2 20 7 1000 5 4.0 0.045 1N5235B 6.8 20 5 750 3 5.0 0.050 1N5236B 7.5 20 6 500 3 6.0 0.058 1N5237B 8.2 20 8 500 3 6.5 0.062 1B5238B 8.7 20 8 600 3 6.5 0.065 1N5239B 9.1 20 10 600 3 7.0 0.068 Device Numbe Maximum Leakage Current IR @ VR Typical Temperature Coefficient (Note 2) vz Nominal Zener Voltage Vz @ Izt (Note 1) Volts %/C 1N5240B 10 20 17 600 3 8.0 0.075 1N5241B 11 20 22 600 2 8.4 0.076 1N5242B 12 20 30 600 1 9.1 0.077 1N5243B 13 9.5 13 600 0.5 9.9 0.079 1N5244B 14 9.0 15 600 0.1 10 0.082 1N5245B 15 8.5 16 600 0.1 11 0.082 1N5246B 16 7.8 17 600 0.1 12 0.083 1N5247B 17 7.4 19 600 0.1 13 0.084 1N5248B 18 7.0 21 600 0.1 14 0.085 1N5249B 19 6.6 23 600 0.1 14 0.086 1N5250B 20 6.2 25 600 0.1 15 0.086 1N5251B 22 5.6 29 600 0.1 17 0.087 1N5252B 24 5.2 33 600 0.1 18 0.088 1N5253B 25 5.0 35 600 0.1 19 0.089 Note 1.
