Type Number Nominal Zener Voltage VZ @ IZT (3) (Volts) Test Current IZT (mA) Maximum Zener Impedance ZZT @ IZT (1) ( Ω) Maximum Regulator Current IZM (2) (mA) Maximum Reverse Leakage Current TA = 25°C IR @ VR = 1V ( µA) TA = 150°C IR @ VR = 1V ( µA) 1N746A 3.3 20 28 110 10 30 1N747A 3.6 20 24 100 10 30 1N748A 3.9 20 23 95 10 30 1N749A 4.3 20 22 85 2 30 1N750A 4.7 20 19 75 2 30 1N751A 5.1 20 17 70 1 20 1N752A 5.6 20 11 65 1 20 1N753A 6.2 20 7 60 0.1 20 1N754A 6.8 20 5 55 0.1 20 1N755A 7.5 20 6 50 0.1 20 1N756A 8.2 20 8 45 0.1 20 1N757A 9.1 20 10 40 0.1 20 1N758A 10 20 17 35 0.1 20 1N759A 12 20 30 30 0.1 20 NOTES: (1) The Zener Impedance is derived from the 1 KHZ AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (IZT) is superimposed on IZT. Zener Impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. (2) Valid provided that leads at a distance of 3/8” from case are kept at ambient temperature. (3) Measured with device junction in thermal equilibrium. |
