5W ZENER DIODE - ON This is a complete series of 5 Watt Zener diodes with tight limits and better operating characteristics that reflect the superior capabilities of silicon−oxide passivated junctions. All this in an axial lead, transfer−molded plastic package that offers protection in all common environmental conditions. Features • Zener Voltage Range − 3.3 V to 200 V • ESD Rating of Class 3 (& gt;16 kV) per Human Body Model • Surge Rating of up to 180 W @ 8.3 ms • Maximum Limits Guaranteed on up to Six Electrical Parameters • Pb−Free Packages are Available* Mechanical Characteristics CASE: Void free, transfer−molded, thermosetting plastic FINISH: All external surfaces are corrosion resistant and leads are readily solderable MAXIMUM LEAD TEMPERATURE FOR SOLDERING PURPOSES: 260°C, 1/16 in. from the case for 10 seconds POLARITY: Cathode indicated by polarity band MOUNTING POSITION: Any 1. Max operating temperature for DC conditions is 150°C, but not to exceed 200°C for pulsed conditions with low duty cycle or non−repetitive. 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 3/8″ 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 (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. 7.
