1N943B [Microchip]

The popular 1N941 thru 1N946B series of Zero-TC Reference Diodes provides a selection of 11.7 V nominal voltages and temperature coefficients to as low as 0.0002%/o C for minimal voltage change with temperature when operated at 7.5 mA. These glass axial-leaded DO-35 reference diodes are also available in JAN, JANTX, and JANTXV military qualifications. Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages from 6.2 V to 200 V.

JEDEC registered 1N941 thru 1N946B series

Standard reference voltage of 11.7 V +/- 5% with tighter tolerances also available

1N941B, 942B, 943B, 944B, 945B also have military qualification to MIL-PRF-19500/157 up to the JANTXV level by adding JAN, JANTX, or JANTXV prefixes to part numbers as well as “-1” suffix, e.g

JANTX1N944B-1, etc

Internal metallurgical bonds

JANS Equivalent available via SCD

Radiation Hardened devices available by changing “1N” prefix to “RH”, e.g

RH944B, RH945B, etc
