DESCRIPTION APPEARANCE
The 1N4765 thru 1N4774A series of Zero-TC Reference Diodes provides a
selection of 9.1 V nominal voltages and temperature coefficients to as low
as 0.0005%/oC for minimal voltage change with temperature when operated
at 7.5 mA. Options for screening similar to JAN, JANTX, JANTXV, and
JANS also exist by using MQ, MX, MV or MSP respectively for part number
prefixes and high reliability screening. Microsemi also offers numerous
other Zener Reference Diode products for a variety of other voltages from
6.2 V to 200 V
DO-7
(DO-204AA)
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES APPLICATIONS / BENEFITS
• JEDEC registered 1N935 thru 1N940 series
• Standard reference voltage of 9.1V +/- 5%
• Internal metallurgical bonds
• JANS Equivalent available via SCD
• Options for screening in accordance with MIL-
PRF-19500 for JAN, JANTX, JANTXV, and
JANS are available by adding MQ, MX, MV, or
MSP prefixes respectively to part numbers. For
example, designate “MX1N4769A” for a JANTX
screen
• Radiation Hardened devices available by
changing “1N” prefix to “RH”, e.g. RH4769A, RH
4774A, etc. Also consult factory for “RH” data
sheet brochure for other radiation hardened
reference diode products.
• Provides minimal voltage changes over a broad
temperature range for instrumentation and other
circuit designs requiring a voltage reference
• Temperature coefficient selections available
from 0.01%/ºC to 0.0005%/ºC
• Tight voltage tolerances available by adding
tolerance 1%, 2%, 3%, etc. after part number for
further identification, e.g. 1N4773A-2%,
1N4774A-1%, 1N4769-3%, 1N4769A-1%, etc.
• Flexible axial-leaded mounting terminals
• Nonsensitive to ESD per MIL-STD-750 Method
1020
MAXIMUM RATINGS MECHANICAL AND PACKAGING

*JEDEC Registered Data.
NOTES:
1. Measured by superimposing IZ ac rms on IZ dc @ +25oC where IZ ac rms = 10% IZ dc.
2. Maximum allowable change between any two discrete temperatures over the specified temperature range.
3. Voltage measurements to be performed 15 seconds after application of dc current.
4. Designate Radiation Hardened devices with “RH” prefix instead of “1N”, i.e., RH4774A.
5. Consult factory for TX, TXV or JANS equivalent SCDs.
