The Zener voltage (Vz) is measured 40 ms after power is supplied. 2. The operating resistances (Zz, Zzk) are measured by superimposing a minute alternating current on the regulated current (Iz). UDZ Series Diodes !Electrical characteristic curves (Ta=25°C) 5.1 5.6 100m 6.2 6.8 8.2 9.1 7.5 15 11 10 12 13 16 18 20 20 10m 1m ZENER CURRENT : IZ (A) 100µ 10µ 1µ 100n 4.7 2.4 10n 0 2.0 2.2 2.7 5 3.0 3.3 4.3 10 15 22 25 30 35 40 ZENER VOLTAGE : VZ (V) Fig.1 Zener voltage characteristics 300 POWER DISSIPATION : Pd (mW) TEMP.
