1N935 thru 1N940B-1, e3
9.0 Volt Temperature Compensated Zener
Reference Diodes
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%/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. 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.
APPEARANCE
DO-7
(DO-204AA)
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES
• JEDEC registered 1N935 thru 1N940 series
• Standard reference voltage of 9.0V +/- 5%
• 1N935B, 937B, 938B, 939B, 940B also have military
qualification to MIL-PRF-19500/156 up to the
JANTXV level by adding JAN, JANTX, or JANTXV
prefixes to part numbers as well as “-1” suffix, e.g.
JANTX1N938B-1, etc.
• Internal metallurgical bonds
• JANS Equivalent available via SCD
• Radiation Hardened devices available by changing
“1N” prefix to “RH”, e.g. RH938B, RH 940B, etc.
Also consult factory for “RH” data sheet brochure
• RoHS compliant devices available by adding an “e3”
suffix (not applicable to military)
APPLICATIONS / BENEFITS
• Provides minimal voltage changes over a broad
temperature range
• For instrumentation and other circuit designs requiring
a stable voltage reference
• Maximum temperature coefficient selections available
from 0.01%/ºC to 0.0002%/ºC
• Tight voltage tolerances available with nominal
voltage of 9.2 V by adding tolerance 1%, 2%, 3%, etc.
after the part number for further identification, e.g.
1N938B-2%, 1N940B-1%, 1N939B-1-1%, etc.
• Flexible axial-leaded mounting terminals
