Type numbers listed have standard tolerance on the nominal zener voltage of ±5%. 2. Measured under thermal equilibrium and DC (IZT) test conditions. 3. The Zener impedance is derived from the 60Hz AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. 1N4728A THRU 1N4764A RATINGS AND CHARACTERISTIC CURVES FIG.1 -- BREAKDOWN CHARACTERISTICS 100 mA 5 10 15 20 25 30 V IZ 80 60 40 20 0 FIG.2 -- ADMISSIBLE POWER DISSIPATION VERSUS AMBIENT TEMPERATURE W 1.0 1N4728 1N4733 1N4735 1N4742 1N4744 1N4747 1N4731 1N4732 1N4739 1N4741 1N4748 1N4749 1N4750 VZ 0.8 Ptot 0.6 0.4 0.2 0 0 100 Tamb 200℃
