1N935 thru 1N940B-1, e3
9.0 Volt Temperature Compensated Zener
Reference Diodes
SCOTTSDALE DIVISION
DESCRIPTION
The popular 1N935 thru 1N940B series of Zero-TC Reference Diodes
provides a selection of 9.0 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-7 reference diodes are
also available in JAN, JANTX, and JANTXV military qualifications. For
commercial applications it is also available as RoHS Compliant with an e3
suffix (not applicable to military). Microsemi also offers numerous other
Zener Reference Diode products for a variety of other voltages from 6.2 V
to 200 V.
