Available HIGH VOLTAGE TEMPERATURE COMPENSATED ZENER REFERENCE DIODES DESCRIPTION The 1N4057 through 1N4085A series of temperature compensated reference diodes provides a wide selection of nominal voltages ranging from 12.4 V to 200 V with low temperature coefficients of either 0%/C or 0%/ o C for minimal voltage change with temperature. This is achieved at the specified test currents of: - ma for the lower voltages 12.4 V to 33 V - ma for the next higher voltage grouping of 37 V to V - 0 ma for 68 V to V - ma for the highest voltage group 105 V to 200 V These axial-leaded reference diodes are packaged in three different plastic body package configurations progressively increasing in size with the voltage. Microsemi also offers numerous other Zener reference diode products in smaller packages for lower voltages in popular JEDEC registrations.

Voltage measurements to be performed 15 seconds after application of dc current. 2. The 1N4057 through 1N4085 series is specified over the temperature range -55 o C to + o C with measurements made at -55 o C, + o C, and at the reference temperature +25 o C. The maximum voltage change over the range -55 o C to +25 o C and +25 o C to + o C for this series is limited to the values (expressed in mv / o C) shown in the table. These values are computed by considering the temperature coefficient to be an average over the temperature range. For example, there is an 80 o C change in temperature from -55 o C to +25 o C. At an average temperature coefficient of 0 %/ o C, the maximum percentage change in voltage would be: 80 o C x 0 %/ o 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.
