Units with guaranteed limits on all seven parameters are indicated by suffix "B" for ±% tolerance..zener OLTGE (z) ND IMPEDNCE (Z ZT & Z ZK ) - Test conditions for zener voltage and impedance are as follows;iz is applied 40±ms prior to reading. Mounting contacts are located from the inside edge of mounting clips to the body of the diode. 3.SURGE CURRENT (Ir) - Surge current is specified as the maximum allowable peak, non-recurrent square-wave current with a pulse width, PW, of 8.3ms. The data given in Fig. May be used to find the maximum surge current for a quare wave of any pulse width between ms by plotting the applicable points on logarithmic paper. Examples of this, using the 6.8v and 0v zeners, are shown in Fig 6. Mounting contact located as specified in NOTE 3. 4.OLTGE REGULTION (z) - Test conditions for voltage regulation are as follows: z measurements are the made at % and then at 0% of the Iz max value listed in the electrical characteristics table. The test currents are the same for the % and % tolerance devices. The test current time druation for each z measurement is 40±ms.Mounting contact located as specified in NOTE..MXIMUM REGULTOR CURRENT (I ZM ) - The maximum current shown is based on the maximum voltage of a % type unit. Therefore, it applies only to the B-suffix device. The actual I ZM for any device may not exceed the value of watts divided by the actual zof the device. T L =7 at 3/8" maximum from the device body.
