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). 100m 200 6.2B 6.8B POWER DISSIPATION : Pd (mW) ZENER CURRENT : Iz (A) 4.7B 5.1B 5.6B 10m 1m 100µ 10µ 1µ 100 50 100n TEMP.
