The popular 1N3154 thru 1N3157A series of Zero-TC Reference Diodes provides a selection of 8.4 V nominal voltages and temperature coefficients to as low as 0.001 %/oC for minimal voltage change with temperature when operated at 10.0 mA. These glass axial-leaded DO-7 reference diodes are also available in JAN, JANTX, and JANTXV military qualifications. As a further option for commercial product, they are available as RoHS Compliant with an e3 suffix added to the part number. Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages from 6.2 V to 200 V.

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.

The popular 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes provides a selection of both 6.4 V nominal voltages and temperature coefficients to as low as 0.0005%/oC for minimal voltage change with temperature. Four different operating currents are available for selection at 0.5 mA, 1.0 mA, 2.00 mA, and 4.00 mA. These glass axial-leaded DO-35 reference diodes are optionally available with an internal-metallurgical-bond by adding a “-1” suffix. This same “-1” bonded Zener package construction is also available in JAN, JANTX, and JANTXV military qualifications. Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages up to 200 V.

The 1N4775 thru 1N4784A series of Zero-TC Reference Diodes provides a selection of 8.5 V nominal voltages and temperature coefficients to as low as 0.0005%/oC for minimal voltage change with temperature when operated at 7.5 mA. Options for screening similar to JAN, JANTX, JANTXV, and JANS also exist by using MQ, MX, MV or MSP respectively for part number prefixes and high reliability screening. Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages from 6.2 V to 200 V.

The popular 1N821 thru 1N829 series of Zero-TC Reference Diodes provides a selection of both 6.2 V and 6.55 V nominal voltages and temperature coefficients to as low as 0.0005%/oC for minimal voltage change with temperature when operated at 7.5 mA. These glass axial-leaded DO-7 reference diodes are also available in JAN, JANTX, JANTXV, and JANS military qualifications. Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages up to 200 V.
