Zener Diode
1N5333B ~ 1N5388B
2. Zener Voltage (VZ) & Impedance (IZT, IZK). Test conditions for zener voltage and impedance are shown in the following: IZ is applied
40 10 ms prior to reading. Mounting contacts are located 3/8” ~ 1/2” from the inside edge of mounting clips to the body of the diode (TA
= 25°C; +8°C/−2°C).
3. Surge Current (ISM). 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 Fig. 5 may be used to find the maximum surge current for a square wave of any PW 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 Fig. 6. Mounting contact located as specified in Note 1 (TA = 25°C; +8°C/−2°C).
4. Voltage Regulation (DVZ). The conditions for voltage regulation are shown in the following: VZ measurements are made at 10%
and then at 50% of the IZM 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 1 (TA = 25°C; +8°C/−2°C).
5. 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 W divided by the actual VZ of the device.
TL = 25°C at 3/8” maximum from the device body.
