1N941-1 thru 1N945B-1

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 %/

C 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.

Available on

commercial

versions

Qualified Levels:
