1. TOLERANCE AND TYPE NUMBER DESIGNATION The JEDEC type numbers shown indicate a tolerance �5%. 2. ZENER VOLTAGE (VZ) and IMPEDANCE (IZT and IZK) Test conditions for zener voltage and impedance are as follows: IZ is applied �10 ms prior to reading. Mounting contacts are located to 1/2 from the inside edge of mounting clips to the body of the diode (TA �2�C). 3. SURGE CURRENT (IR) Surge current is specified as the maximum allowable peak, non�recurrent square�wave current with a pulse width, PW, of 8.3 ms. The data given in Figure 6 may be used to find the maximum surge current for a square wave of any pulse width between 1 ms and ms by plotting the applicable points on logarithmic paper. Examples of this, using the 3.3 V and 200 V zener are shown in Figure 7. Mounting contact located as specified in Note 2 (TA �2�C). 4. VOLTAGE REGULATION (DVZ) The conditions for voltage regulation are as follows: VZ measurements are made at 10% and then 50% of the IZ max value listed in the electrical characteristics table. The test current time duration for each VZ measurement 40 �10 ms. Mounting contact located as specified in Note 2 (TA �2�C). 5. MAXIMUM REGULATOR CURRENT (IZM) The maximum current shown is based on the maximum voltage a 5% type unit, therefore, it applies only to the B�suffix device. The actual IZM for any device may not exceed the value of 5 watts divided by the actual VZ of the device. at 3/8 maximum from the device body. *Not Available in the 2000/Ammo Pack.
