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) 100m 4.7B 5.1B 5.6B 6.2B 6.8B 200 POWER DISSIPATION : Pd (mW) ZENER CURRENT : Iz (A) 10m 1m 100 CAPACITANCE BETWEEN TERMINALS : CT (PF) 100 4.7B 100µ 10µ 1µ 100n 1 2 3 4 5 6 7 50 10 5.1B 5.6B 6.2B 6.8B 0 0 25 50 100 150 0 1 10 ZENER VOLTAGE : Vz (V) AMBIENT TEMPERATURE : Ta (°C) REVERSE VOLTAGE : VR (V) Fig. 1 Zener characteristics Fig. 2 Derating curve Fig. 3 Capacitance between terminal characteristics TEMP.
