ZENER VOLTAGE (V ) and IMPEDANCE (I and I ): Test conditions for zener voltage and impedance are as follows: I is applied Z ZT ZK Z 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 (T = 25C +8C, 2C). A 4. SURGE CURRENT (I ): Surge current is specified as the maximum allowable peak, nonrecurrent squarewave current with a pulse width, R 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 (T = 25C +8C, 2C). A 5. VOLTAGE REGULATION ( V ): The conditions for voltage regulation are as follows: V measurements are made at 10% and then at 50% Z Z of the I max value listed in the electrical characteristics table. The test current time duration for each V measurement is 40 10 ms. Mounting Z Z contact located as specified in Note 2 (T = 25C +8C, 2C). A 6. MAXIMUM REGULATOR CURRENT (I ): The maximum current shown is based on the maximum voltage of a 5% type unit, therefore, ZM it applies only to the Bsuffix device. The actual I for any device may not exceed the value of 5 watts divided by the actual V of the device. ZM Z T = 25C at 3/8 maximum from the device body.
