Available on
commercial
versions
11.7 Volt Temperature Compensated
Zener Reference Diodes
Qualified per MIL-PRF-19500/157
DESCRIPTION
The popular 1N941-1 thru 1N945B-1 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. The “B” version of these glass,
axial-leaded DO-35 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 from 6.2 V to 200 V.
Qualified Levels:
JAN, JANTX,
JANTXV and JANS
(available on some part
numbers)
