1N941 thru 1N946B-1
11.7 Volt Temperature Compensated Zener
Reference Diodes
SCOTTSDALE DIVISION
APPEARANCE
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%/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, 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.
