DESCRIPTION APPEARANCE
The 1N4057 thru 1N4085A series of Zero-TC Reference Diodes provides a
wide selection of nominal voltages ranging from 12.4 V to 200 V with low
temperature coefficients of either 0.005%/C or 0.002%/oC for minimal voltage
change with temperature. This is achieved at the specified test currents of
10.0 mA for the lower voltages 12.4 V to 33 V, a specified test current of 7.5
mA for the next higher voltage grouping of 37 V to 100 V, 5.00 mA for 68 V to
100 V, and 2.5 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.

NOTES:
*JEDEC Registered Data
1. Voltage measurements to be performed 15 seconds after application of dc current.
2. The 1N4057 through 1N4085 series is specified over the temperature range -55oC to +100oC with measurements made at -55oC, +100oC, and at
the reference temperature +25oC. The maximum voltage change over the range -55oC to +25oC and +25oC to +100oC for this series is limited to
the values (expressed in mV/oC) 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 80oC change in temperature from -55oC to +25oC. At an average temperature coefficient of
0.005%/oC, the maximum percentage change in voltage would be: 80oC x 0.005%/oC 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.
