1N944BE3 [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

Also consult factory for “RH” data sheet brochure
