NOTE? Voltage measurements to be performed 15 seconds after application of DC current. NOTE2 The 1N4057 through 1N4085 series is specified over the temperature range -55°C to +100°C with measurements made at -55°C, +100°C, and at the reference temperature +25°C. The maximum voltage change over the range -55°C to +25°C and +25°C to +100°C for this series is limited to the values (expressed in mV/°C) shown in the table on the reverse page. These values are computed by considering the temperature coefficient to be an average over the temperature range. For example, there isan 80°C change in temperature from -55°C to+25°C. Atan average temperature coefficient of 0.005%/°C, the maximum percentage change in voltage would be: 80°C x 0.005%/°C or 0.4%. For the 1N4057, having a nominal zener voltage of 12.4 volts, the maximum allowable voltage change would be: 0.4% of 12.4 volts or 49.6 millivolts.
