Description

General part information

1N945B-1-Zener-Diode Series

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.
