The Zener voltage (Vz) is measured 40ms after power is supplied. 2. The operating resistances (Zz, Zzk) are measured by superimposing a minute alternating current on the regulated current (Iz). ! ! ! !Electrical characteristic curves (Ta = 25 °C) Fig.1 Zener voltage characteristics 10n 100n 1 µ 10 µ 100 µ 1m 10m 100m ZENER VOLTAGE : VZ (V) 0 5 10 15 300 200 100 0 050 25 100 150 AMBIENT TEMPERATURE : Ta ( °C) Fig.2 Derating curve Fig.3 Zener voltage-temp. coefficient characteristics ∗UDZS series : VZ = 5.1V~10V −0.08 −0.06 −0.04 −0.02 0.00 0.02 0.04 0.06 0.08 0.10 Iz=5mA Iz=500 µA 210 20 30 ZENER VOLTAGE : Vz (V) |
