ZENER VOLTAGE (VZ) and IMPEDANCE (IZT and IZK): Test conditions for zener voltage and impedance are as follows: IZ is applied 40 ±10 ms prior to reading. Mounting contacts are located 3/8″ to 1/2″ from the inside edge of mounting clips to the body of the diode (TA = 25°C +8°C, −2°C). 4. 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 5 may be used to find the maximum surge current for a square wave of any pulse width between 1 ms and 1000 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 6. Mounting contact located as specified in Note 2 (TA = 25°C +8°C, −2°C). 5. VOLTAGE REGULATION ((cid:2)VZ): The conditions for voltage regulation are as follows: VZ measurements are made at 10% and then at 50% of the IZ max value listed in the electrical characteristics table. The test current time duration for each VZ measurement is 40 ±10 ms. Mounting contact located as specified in Note 2 (TA = 25°C +8°C, −2°C). 6. MAXIMUM REGULATOR CURRENT (IZM): The maximum current shown is based on the maximum voltage of 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. TL = 25°C at 3/8″ maximum from the device body. †The “G’’ suffix indicates Pb−Free package or Pb−Free packages are available. http://onsemi.com 2
