Devices listed in bold, italic are ON Semiconductor Preferred devices. Preferred devices are recommended choices for future use and best overall value.
2. TOLERANCE AND TYPE NUMBER DESIGNATION: The JEDEC type numbers shown indicate a tolerance of ±5%.
3. 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 3/8to 1/2from 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, nonrecurrent squarewave 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 (DVZ): 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 Bsuffix 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 3/8maximum from the device body.
